What you'll need
- An active Gemini account (email or phone linked)
- Your account password
- Access to your second factor (Authenticator app, SMS, or hardware key) if enabled
Step-by-step: How to sign in
- Open the Gemini website or mobile app and click Sign in.
- Enter the email address or phone number associated with your account.
- Type your password. If you use a password manager, autofill is safe when using your personal device.
- If you have two-factor authentication (2FA) enabled, complete the 2FA step.
- When signed in, verify your account details and check for any security alerts.

Two-factor authentication (2FA)
2FA protects your account by requiring a second proof of identity. Common options:
- Authenticator app (recommended): Google Authenticator, Authy, or similar — generates time-based codes.
- SMS: convenient but less secure due to SIM-swapping risks.
- Hardware security key (FIDO2 / WebAuthn): strongest option for protection.
Troubleshooting
Forgot password
Use the "Forgot password" link on the sign-in page. Gemini will send reset instructions to your registered email. If you don't receive the email, check spam and verify the address you used.
Unable to receive 2FA codes
- Try a backup method (backup codes or an alternate device).
- If using an authenticator app, make sure device clock is accurate (set to automatic time).
- Contact Gemini support if you cannot recover access; expect identity verification steps.
Security best practices
- Enable strong 2FA (prefer authenticator app or hardware key).
- Use a unique, high-entropy password. Consider a password manager.
- Never share your private keys, recovery phrases, or 2FA backup codes with anyone.
- Verify URLs and bookmarks — phishing sites often mimic legitimate pages.
- Keep your OS and browser up to date.
