Logging In with a New Phone (Same Phone Number)

Using Passkey for 2FA:

If your passkey was set up to be cross-device using cloud services to store the passkey (i.e. iCloud, Google Password Manager, 1Password, Bitwarden, etc.), then you do not require a new passkey setup.

If your passkey was set up to be device-specific (i.e. stored in your Google Chrome browser, Windows Hello, etc.), then you need to log back into the device to create a new passkey using your phone or cloud credential storage providers which can be synced cross-device.

Using Authenticator App for 2FA:

Install your preferred authenticator app (Google Authenticator, Duo Mobile, etc.) on your new phone. Sign in to your authenticator app account. If your authenticator app was backed up to the cloud or has a native recovery mechanism within the authenticator app, Gemini will appear in the application list within your authenticator app on the new device which you can continue to use to sign in.

If you don’t have your authenticator app backed up, you will need to either change this setting in the old device (preferred) or go through support to get you back into the app.

Using Authy for 2FA:

1. Reinstall the Authy App:
   • Uninstall Authy from your old device.
   • Go to the Authy Creation Page to download and install the Authy app on your new device.
2. Set Up Authy:
   • Open the Authy app and enter the same phone number registered with your Gemini account.
   • Enter the verification code sent via SMS to your phone.
   • Your Authy token will appear in the app.
3. Upgrade to Passkeys (Recommended):
   • After setting up Authy, we recommend upgrading to Passkeys for a faster and more secure authentication experience.
   • Go to Settings > Security in your Gemini account to set up Passkeys.
4. Troubleshooting:
   • If you don’t receive the SMS or encounter issues, please reset your account at the Authy Reset Page.

Changing Your Phone Number

In order to change your phone number (whether you opted to receive your 2FA codes via SMS or push notifications) in Gemini, the process depends on whether you have Passkeys set up or if you are using Authy for 2FA.

If you have Passkeys set up, please open a support ticket here to let our support team know of the updated phone number so we can update your account information.

If you do not have Passkeys set up, the steps to changing your phone number in Authy are as follows

1. Navigate to this link.
2. Input your old phone number and your new phone number.
3. Then, you will receive an email from noreply@authy.com to your email address associated with your account to confirm this change was one you made.
4. After Authy confirms the phone number change it typically takes 3-4 business days to process. During this time, please do not log in/access your Authy account as this may result in delays or rejection of your phone number change request.

Please note, if you go to your Authy app and receive a notification that your Multi-device is disabled for your account, you will need to visit https://www.authy.com/phones/reset in order to recover your Authy account. Once you begin the reset process, you will receive SMS text message updates on the progress from Authy.

After Authy has completed updating to your new phone number, please open a support ticket here to let our support team know of the updated phone number so we can update your account information.
