A password manager limits the damage from a stolen password by helping you use a different, strong password for every service. Passkeys add another layer: at services that support them, they replace passwords with site-specific cryptographic credentials designed to resist phishing. Use both where they fit, and protect the manager vault itself.
How do password managers limit the damage from a stolen password?
If you reuse a password and one service is breached, attackers may try that same username-and-password combination on other services. This is called credential stuffing. A password manager helps prevent that chain reaction by generating and storing a distinct password for each account. NIST says well-designed password managers encourage unique, complex passwords, helping protect against password guessing, cracking, and password-spraying attacks. NIST Digital Identity Guidelines Implementation Resources FAQ
The manager does not prevent a service from being breached, stop every kind of account takeover, or make stored credentials invulnerable. It reduces the chance that one exposed password will unlock other accounts. NIST describes password managers as offering greater security and convenience, while warning that compromise of the master secret can mean replacing the passwords stored in the vault. NIST SP 800-63 Digital Identity Guidelines FAQ
Are passkeys safer than passwords?
Passkeys are designed to resist phishing. Rather than entering a reusable password, you authenticate with a site-specific cryptographic credential, typically using your device’s unlock method. A passkey for one service is not simply a password an attacker can reuse at another. NIST’s consumer guidance says passkeys cannot be easily stolen through phishing and do not require memorization.

- ✅ PROTECT ONLINE ACCOUNTS – A password manager, two-factor security key, and secure communication token in one, OnlyKey can keep your accounts safe even if your computer or a website is compromised. OnlyKey is open source, verified, and trustworthy.
- ✅ UNIVERSALLY SUPPORTED – Works with all websites including Twitter, Facebook, GitHub, and Google. Onlykey supports multiple methods of two-factor authentication including FIDO2 / U2F, Yubico OTP, TOTP, Challenge-response.
- ✅ PORTABLE PROTECTION – Extremely durable, waterproof, and tamper resistant design allows you to take your OnlyKey with you everywhere.
- ✅ PIN PROTECTED – The PIN used to unlock OnlyKey is entered directly on it. This means that if this device is stolen, data remains secure, after 10 failed attempts to unlock all data is securely erased.
- ✅ EASY LOG IN –No need to remember multiple passwords because by plugging OnlyKey to your computer, it automatically inputs your username and password. It works with Windows, Mac OS, Linux, or Chromebook, just press a button to login securely!
NIST describes correctly implemented syncable authenticators as phishing-resistant and notes potential cross-device and recovery benefits. But passkey support, storage, syncing, recovery, and migration differ by service and implementation. Set up a passkey where offered, then check how you can use it on your other devices and regain access if a device is lost.
Passkeys and password managers are complementary, not competing choices. Use passkeys for supported accounts; keep a password manager for accounts that still require passwords and for other stored secrets. A manager may also store or sync passkeys, depending on its features, but do not assume all passkeys have the same portability or recovery options.

How do I choose a password manager?
There is no universally best storage model. Choose a manager that works with your devices and browsers, can generate unique passwords, secures its vault, supports MFA, and has recovery and backup options you understand. Compare these practical considerations:
- Device and browser support: Confirm it works on the devices and browsers you actually use, including any work or shared devices where you intend to sign in.
- Cloud sync or local storage: Cloud sync can make credentials available across devices but relies on the provider’s infrastructure. A locally maintained database gives you more direct responsibility for storage, but requires dependable backups and care to avoid loss or user error. CISA discusses these trade-offs in its guidance on password managers.
- Vault protection and MFA: Review how the vault is protected and whether you can enable MFA for your manager account.
- Recovery and export: Understand what happens if you forget the vault passphrase or lose a device. Check whether you can export credentials or back up a local database, and store recovery material securely.
- Usability and accessibility: A manager must be practical to use consistently. Consider its accessibility, how it fills logins, and how easily you can change reused passwords.
How do I set up the manager and secure my accounts?
- Inventory accounts and start with the ones that matter most. Begin with email, financial, work, and mobile-carrier accounts. Access to these may help someone reach or recover other accounts; this is a practical prioritization, not a quantified risk ranking.
- Choose a manager and learn its recovery process. Confirm device compatibility, vault protection, MFA availability, and backup or recovery options before moving credentials into it.
- Set a long, unique vault passphrase and enable MFA. Do not reuse a password from another service for the vault. If the manager offers MFA, turn it on. Secure recovery material separately and understand the recovery steps; recovery methods can have their own risks.
- Replace reused and weak passwords. Generate a different password for each account, starting with important accounts. NIST’s consumer guidance says a password a person creates should be at least 15 characters long. For generated passwords, use the manager’s generator and prioritize uniqueness rather than trying to memorize each one.
- Add passkeys where services support them. Follow each service’s account-security settings to create a passkey. Test it on the devices you use and confirm the service’s recovery and device-migration options.
- Keep MFA on accounts that still use passwords. Prefer phishing-resistant options where available. CISA identifies FIDO/WebAuthn authentication as a widely available phishing-resistant option; support depends on the account and device.
What should I do if a password is exposed?
For the affected service, change the password to a new, unique one generated by your manager. Where the service allows it, revoke active sessions so existing logins are ended. Review the account’s recovery settings and MFA, and check that recovery email addresses or phone numbers are still yours. If the exposed password was reused, change it everywhere else it was used as well.

- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
These are practical response steps, not a universal service-specific procedure: available controls differ. For accounts protected by passkeys, review the service’s registered passkeys and recovery options instead of assuming a password change alone addresses every access route.

A FIDO2/WebAuthn hardware security key can be a useful physical authenticator for an account that supports it. Check that the service accepts security keys and that the key’s connector and standards work with your devices. CISA’s mobile communications guidance discusses this option. CISA mobile communications best practices
A key is optional, not a substitute for checking account support and planning recovery. If you rely on one, understand what you will use to regain access if it is lost.
