MFA and Account Recovery: A Practical Checklist

A strong password is only one layer of account security. MFA can add another barrier, while a recovery plan helps you regain access without creating an easy path for an attacker.

1. Protect your primary email first

Your email account often controls password resets for many other services. Give it a unique password, enable the strongest MFA method the provider supports, and keep recovery information current.

2. Prefer phishing-resistant authentication

FIDO/WebAuthn security keys and passkeys can resist many common phishing attacks because authentication is bound to the legitimate service. CISA recommends phishing-resistant MFA where feasible. Authenticator apps remain useful when stronger options are unavailable; SMS is a weaker fallback because it is not phishing-resistant and can be exposed to telecom-account attacks.

3. Store recovery codes safely

When a service offers one-time backup codes, save them somewhere secure and separate from the phone you normally use for MFA. A protected password manager or an offline copy kept in a secure physical location may be appropriate depending on your risk and recovery needs.

4. Test your recovery plan before you need it

Confirm that backup authentication methods work before replacing or resetting a phone. If you use hardware security keys, consider registering a second key and storing it separately. Review unfamiliar sessions and devices while you still have access.

5. Do not weaken recovery to make it convenient

A strong sign-in method can be undermined by an easy recovery route. Treat recovery email accounts, phone numbers, help-desk verification, and backup codes as part of the authentication system.

6. Know what MFA cannot stop

Malware, stolen sessions, deceptive approval prompts, compromised recovery channels, and an already-unlocked device can still lead to account compromise. Be suspicious of unexpected sign-in prompts and use official service URLs rather than links in unsolicited messages.

Next: create a strong password, understand password managers, or generate a random password.
