A lost, stolen, or reset phone does not normally erase cryptocurrency held on a blockchain. Recovery depends on what controlled the wallet: a self-custody recovery phrase or private key, an identity-backed embedded or smart wallet, or an exchange account. First lock down the missing phone and related accounts. Then restore the wallet only through its official app, or complete the exchange’s account-recovery process. If a thief may have seen your phrase or unlocked the wallet, create a new wallet and move the assets immediately.
What determines whether recovery is possible
The app on your phone is usually only an interface. In a self-custody wallet, the signing keys are recreated from a Secret Recovery Phrase (also called a seed or mnemonic phrase) or from an individually imported private key. The blockchain balance remains associated with those keys when the phone is wiped or replaced.
Other arrangements work differently. An embedded or smart wallet may protect recovery material with an email or social login, a password, a passkey, or a cloud backup. Coins held by a centralized exchange are tied to the exchange account; you recover that account rather than importing an exchange password into a wallet app.
| Wallet arrangement | What controls access | Recovery material or process | Correct next action after phone loss |
|---|---|---|---|
| Self-custody wallet | Your private keys | Secret Recovery Phrase; an imported account may also require its private key | Install the official wallet app and restore or import the existing wallet |
| Embedded wallet | Provider-managed encryption linked to an identity | Same email, Google, Apple, Telegram, password, or passkey method required by the provider | Use the provider’s exact sign-in and restoration flow on a secure device |
| Smart wallet | Programmable signers, often including a passkey | Cloud-backed passkey and, where supported, an optional recovery phrase that can add a signer | Recover the passkey or use the recovery-phrase signer flow specified by the provider |
| Exchange account | The exchange’s account system | Account credentials, identity checks, and replacement two-step verification | Use the exchange’s official account-recovery process; do not import the password into a self-custody wallet |
Secure the missing phone and linked accounts first
Contain the risk before attempting a restore. A phone that is merely misplaced is a recovery problem; a phone that may be unlocked is a possible key-exposure incident.
#1 Best Overall
- Effortlessly build your crypto portfolio via the all in one Ledger Wallet app: buy, sell, send, receive, swap, stake and more across popular blockchains. 15,000+ coins & tokens in a single dashboard. Keep a close eye on the market. Compare service providers. Track performance. Get timely alerts. Build your portfolio with confidence.
- Enjoy Bluetooth connectivity, iOS access, and hours of battery use with this mobile-first, secure backup signer. Freedom you can depend on.
- Genuine Check: confirm your signer is authentic during setup with the Ledger Wallet app.
- Protect your signer: keep it in mint condition at all times with a bespoke Pod or Case to avoid scratches and everyday wear and tear.
- Lock or erase the device. Use Apple Find My for an iPhone or Google’s device-management tools for an Android phone. If recovery is unlikely, remote erasure reduces the chance that someone can open wallet or email apps.
- Sign out and change the primary account password. Google specifically recommends signing out of the lost or stolen phone and changing the Google Account password. Apply the equivalent controls to the Apple Account and any email account used for wallet recovery.
- Recover your mobile number. Ask the carrier to move the number to a replacement SIM or eSIM if it is needed for account verification. Add a carrier account PIN where available.
- Protect exchange and cloud sessions. From a trusted computer or replacement phone, revoke sessions you do not recognize, change passwords, and replace lost two-step-verification methods.
- Use only official software and support. Download the wallet or exchange app from its verified publisher and navigate to support from the service’s own app or a site you entered yourself. Do not follow recovery links sent by strangers.
Do not enter a recovery phrase while the old phone, browser, or network may be monitored. Use a clean replacement device, update its operating system, and enable a screen lock before restoring anything.
Restore a self-custody wallet
What you need
You need the wallet’s original Secret Recovery Phrase, in the correct order and spelling. An account imported from another wallet may not be recreated by the phrase alone; that account’s private key can be required separately. You may also need the wallet password that encrypts local data, although a password by itself cannot recreate a wallet on a new device.
Step-by-step restoration
- Prepare a clean replacement phone. Install operating-system updates, set a strong device passcode, and avoid restoring unknown apps or browser extensions.
- Install the wallet from its official source. Check the publisher name and spelling carefully. A convincing look-alike app can steal a phrase during setup.
- Choose the existing-wallet option. Labels vary by product: look for Import existing wallet, Restore wallet, Import using Secret Recovery Phrase, or an equivalent choice. Do not select “create new wallet” unless you intend to make a separate wallet.
- Enter the phrase offline and privately. Type the words in order. Never photograph them, paste them into a website, store them in a chat, or send them to support.
- Set a new local password. This password protects the app on the replacement phone; it is not a substitute for the recovery phrase.
- Import separately held accounts. If an account was added with a private key rather than derived from the phrase, use the wallet’s official import-account function and the original private key.
- Re-add networks and tokens. A restored wallet may show only its default network and accounts. Add other supported networks through the wallet’s normal settings and add token contracts only from trusted project information.
- Verify before transacting. Compare the restored public addresses with an old transaction record or a trusted address book. Send a small test amount only after the address and network match.
MetaMask-specific points
MetaMask’s official instructions state that a fresh installation can be restored with the Secret Recovery Phrase. If the wallet was created through MetaMask’s supported Google, Apple, or Telegram login flow, sign in with the same identity and provide the required wallet password. Additional networks, tokens, and accounts may need to be added manually after sign-in.

A phone reset does not transfer assets to a new wallet and does not change the blockchain addresses. It removes the local app data; restoring the same keys recreates access to the same accounts.

Recover an embedded or smart wallet
Embedded wallets tied to an identity
Some services encrypt wallet material behind an identity account rather than showing a traditional seed phrase during setup. Kraken says an embedded wallet can be restored on a secure replacement device by signing in with the same email, Google, Apple, or passkey method. Use precisely the identity and authentication method originally enrolled; a different email address can create a different wallet.
- Install the provider’s official app or open its verified website on the clean device.
- Select sign-in or wallet restoration, not new-wallet creation.
- Use the same identity provider and complete multi-factor checks.
- Approve any device-enrollment or recovery prompts and set a new local lock.
- Confirm that the displayed addresses and balances match records from the old device before sending funds.
Smart wallets with passkeys
Coinbase says a smart wallet may use a cloud-backed passkey and an optional recovery phrase. The passkey can restore access when it is available through the account’s cloud synchronization. If the passkey or device is lost, the optional recovery phrase can add a new signer according to the provider’s procedure. Follow that procedure exactly; do not paste the phrase into an unsolicited form or message.
Because smart-wallet rules differ, read the provider’s in-app recovery explanation before approving a signer change. A signer-recovery transaction can be irreversible, so check the destination address and the network shown on a trusted screen.

If the coins were held on a centralized exchange, the exchange controlled the account keys on its platform. Ethereum.org explains that exchanges may be able to help with password or account recovery, unlike a self-custody wallet provider that does not possess your phrase.

If the phone or recovery phrase may have been exposed
Assume compromise when a thief could know the device passcode, unlock the wallet, view an unencrypted phrase, or access a cloud account that protects a passkey. A remote wipe is useful containment, but it cannot undo a phrase that someone already copied.
- Create a brand-new wallet on a secure device. Generate a new phrase; do not reuse the old one.
- Confirm the new receiving addresses. Record them offline and verify the network for each asset.
- Transfer assets from the potentially exposed wallet. Move funds in priority order, starting with assets at greatest risk. Keep enough native-network currency to pay transaction fees.
- Revoke token approvals. If the old wallet may have been unlocked, review and revoke allowances using a trusted tool for each relevant network.
- Stop using the exposed wallet. Treat it as unsafe even if no theft has appeared. Watch its addresses for later activity.
Kraken specifically recommends creating a new wallet and transferring funds when the phrase or device passcode may have been exposed. The transfer protects the assets; changing a password inside the compromised wallet does not replace its keys.

For a true self-custody wallet, there is no central reset function. MetaMask states, “MetaMask cannot recover your wallet for you.” Ethereum.org likewise states, “No one, including ethereum.org, can reset your password or restore access to a self-custody wallet.” A person offering paid seed-phrase recovery is asking for the one secret that controls the funds and should be treated as a scam risk.

Before concluding that the phrase is gone, check only your own secure records: a correctly labeled paper backup, a fire-resistant backup, a password manager entry you deliberately created, or another offline copy. Check word order, spelling, and whether the wallet used an additional passphrase. Do not test the phrase on random websites. If every legitimate copy is missing and no supported identity recovery exists, the wallet may be permanently inaccessible.

- Never disclose a Secret Recovery Phrase, private key, wallet password, exchange password, backup code, or one-time code to “support” or to anyone who contacts you first.
- MetaMask says it will never ask for your Secret Recovery Phrase. The same rule is a safe baseline for every legitimate wallet provider.
- Ignore direct messages promising to trace, unlock, or recover funds for an upfront fee.
- Verify app publishers, domains, email addresses, and support contacts independently. A padlock icon or a search-engine advertisement does not prove authenticity.
- Do not approve a transaction merely because a recovery page says it is required. Read the network, recipient, amount, and permissions on a trusted screen.
- Move funds only after comparing the destination address character by character or using a trusted address-book entry. Malware can replace an address copied to the clipboard.
Check the restored wallet before declaring success
A successful login is not proof that you restored the right account. Use this verification sequence:
- Compare each public address with an old receive record, transaction hash, tax export, or other trusted record.
- Confirm the correct network. The same account can have different balances on different networks, and a token can appear missing when the network is simply not selected.
- Re-add accounts one at a time and label them clearly. Do not assume the first account is the only one you used.
- Inspect recent transactions and approvals for unexpected activity.
- Back up the phrase again offline before uninstalling anything or changing devices.
- Perform a small test receive or send only after all details match.
Prevent the next device-loss emergency
- Keep the recovery phrase offline in a secure location. Maintain a second physically separate backup when that fits your threat model.
- Never store an unencrypted phrase in a photo library, email draft, cloud note, or ordinary text file.
- Consider a hardware wallet for long-term holdings. Hardware wallets keep signing keys offline, but they still depend on a protected recovery phrase. MetaMask names Ledger and Trezor as examples.
- For Google or Apple accounts that protect an embedded wallet, save backup codes and consider a spare hardware security key.
- Google lists backup codes and security keys as fallback methods. Apple recommends setting up at least two security keys so one remains available if another is lost, damaged, or stolen.
- Apple also documents Account Recovery Contacts, who can provide a recovery code out of band.
- Record wallet addresses and transaction histories without recording secret keys in the same place. This makes post-recovery verification easier.
- Rehearse the restoration process with an empty test wallet so you know which accounts, networks, and tokens must be added.
Quick decision guide
| What happened | What you still control | Best next move |
|---|---|---|
| Phone lost or reset, no sign of exposure | Original phrase, private key, or supported identity login | Secure accounts, then restore on a clean device |
| Phone stolen and likely unlocked | Original phrase or another secure copy | Create a new wallet and transfer funds; treat the old wallet as exposed |
| Embedded or smart wallet device lost | Same identity account, passkey, or optional recovery phrase | Use the provider’s identity or signer-recovery flow |
| Funds held on an exchange | Exchange identity and verification documents | Recover the exchange account, replace two-step verification, and audit activity |
| Self-custody phrase and private key both unavailable | No usable recovery material | No provider reset exists; beware anyone offering paid recovery |
The Bottom Line
Secure the lost phone and linked accounts first, identify the custody model, and restore only with the original recovery material or the provider’s documented identity flow. If a phrase or passcode may have been exposed, migrate assets to a newly generated wallet instead of trying to secure the old one. Whoever controls the recovery material controls a self-custody wallet.
