Enable two-factor authentication (2FA) from your exchange’s official website or app: open its Security or 2FA settings, choose a supported method, follow the enrollment prompts, and complete the service’s confirmation step. Menu names and available methods vary by exchange and product, so use that exchange’s current instructions and set up a recovery route before relying on a single device.
Before you start
- Open the exchange’s genuine website or official app and sign in directly. Avoid security links in unsolicited messages; phishing is a risk Coinbase addresses in its account security guidance.
- Have access to the device or method you plan to enroll. For an authenticator app, you will need to scan or enter the setup information shown by the exchange.
- Check how the exchange handles account recovery if your phone, key, or passkey becomes unavailable. Recovery steps differ, and the cited providers do not establish a universal backup-code process.
Enable 2FA: the common setup flow
- Sign in through the official exchange site or app. Do not use a link from a text, email, or direct message to reach the sign-in page.
- Open the account’s Security, 2FA, or 2-step verification settings. The exact label and path depend on the exchange, and may differ between its retail app and exchange product.
- Choose a method the exchange supports. Options may include a passkey, hardware security key, authenticator app, SMS, push notification, or email. Not every exchange offers every method, and some methods may apply only to particular actions.
- Follow the enrollment prompt. For an authenticator app, the exchange commonly displays a QR code or setup secret. Add it to the app, then enter the generated code on the exchange to confirm. Treat the QR code and secret like credentials: anyone who obtains them may be able to provision the same factor.
- Complete the exchange’s test or confirmation. Do not assume enrollment is finished until the interface confirms it. Review the exchange’s recovery instructions while you are still signed in, and make sure you can use the enrolled factor before signing out.
Choose a method the exchange supports
Factor choice is provider- and account-specific. Coinbase lists security keys, passkeys, authenticator apps, push notifications, and SMS in its 2-step verification guidance. Kraken documents passkeys, hardware security keys, and authenticator apps. Check the current settings for your account rather than assuming a method is available.
| Method | What it does and what to check |
|---|---|
| Passkey | Uses cryptography for sign-in. Kraken describes passkeys as phishing-resistant because they work on Kraken’s real site rather than providing a code to enter elsewhere; Coinbase also lists passkeys among its methods. Confirm how your exchange handles passkey access and recovery if you lose or replace a device. |
| Hardware security key | A physical key can be used where the exchange supports it. Coinbase says it supports U2F security keys and names YubiKey as an example; Kraken also documents hardware keys. Verify compatibility with the exchange, your browser or device, and the relevant account flow before buying or enrolling a key. |
| Authenticator app (TOTP) | The app generates time-based codes. Coinbase Exchange and Binance document QR-code enrollment followed by code confirmation. This is a practical option when supported, but the codes are not phishing-resistant; Kraken makes this distinction in its authenticator app explanation. Keep the enrollment secret private and plan for loss of the device using the exchange’s recovery process. |
| SMS or phone | Some provider flows include phone or SMS verification. Availability differs, and the documentation cited here does not establish it as equally protective across providers. Follow the exchange’s guidance and do not assume SMS is its only or preferred option. |
| Push or email | These may be offered in specific products or for particular actions. Coinbase lists push notifications; Binance lists email among methods in its action-specific verification strategy. Their availability and role are not universal. |
Coinbase’s security guidance recommends security keys or passkeys and describes TOTP as an alternative. These are vendor recommendations, not a guarantee against every form of account compromise. Kraken similarly characterizes passkeys as phishing-resistant in its sign-in 2FA guidance.
Official exchange examples
Coinbase Exchange: authenticator app
Coinbase Exchange has a dedicated authenticator setup flow; it should not be treated as the universal path for every Coinbase retail account. Its Exchange instructions direct users to the profile security page, select Set Up for Authenticator app, approve the change using existing verification, scan the QR code, enter the six-digit code, and enable the method. The page also notes that users on shared accounts may need to enroll their own devices.

Binance app: authenticator setup
Binance’s authenticator instructions start at Account, then profile, then Security; the user verifies the generated six-digit authenticator code. Labels and availability can change, so follow the live in-app or help-center prompts.
Binance separately documents a 2FA Verification Strategy feature that assigns verification methods to actions such as login, assets, account settings, and security management. Its stated requirements—completed KYC and more than 100 USDT in the account—apply to that specific feature, not to standard authenticator enrollment. See Binance’s verification strategy instructions.

If setup does not work
- The setting is missing: Confirm that you are in the correct exchange product and account profile. Retail and exchange interfaces can use different paths; consult that product’s official help page.
- The authenticator code is rejected: Confirm that the authenticator entry belongs to the correct exchange account and that you are entering the current code. If the exchange offers a fresh enrollment prompt, follow its instructions rather than reusing an old setup secret.
- You cannot use the enrolled factor: Follow the exchange’s current account-recovery process. Do not assume another method or a backup-code feature exists unless the exchange documents it for your account.
- You suspect a fake page or exposed setup secret: Stop entering codes on that page. Navigate to the official exchange directly and follow its security guidance; treat an exposed authenticator QR code or secret as a compromised credential.
