You have several ways you can get back into your account, depending on your circumstances.

Use backup options

If you've lost access to your primary phone, you can verify it’s you with:

• Another phone signed in to your Google Account.

• Another phone number you’ve added in the 2-Step Verification section of your Google Account.

• A backup code you previously saved.

• A security key you’ve added in the 2-Step Verification section of your Google Account.

Sign in from a trusted device

If you previously signed in from a device and checked the box next to “Don’t ask again on this computer,” you might be able to sign in from that device without a second verification step. After you sign in to your Google Account, you can manage your verification methods.

Recover your account

If you can’t sign in, follow the steps to recover your account. If you're having trouble, try the tips to complete account recovery steps.

Choose the right steps to get back into your account, based on if you set up another second step, like:

• Verification codes

• Google prompts

• Backup codes

• A backup security key you’ve added to your account

• A registered computer where you chose not to be asked for a verification code

Important: If you added Advanced Protection to your account, you can only use a backup security key. If you don’t have a backup security key, follow the steps to recover your account.

If you have another second step

1. Sign in to your Google Account with your password and your other second step.

2. Follow the steps to remove the lost key from your account.

3. Get a new security key. You may want to get an extra key you can keep in a safe place.

4. Add the new key to your account.

If you don’t have another second step or forgot your password

Important: 2-Step Verification requires an extra step to prove you own an account. Because of this added security, it can take  3-5 business days for Google to make sure it’s you.

Follow the steps to recover your account. You'll be asked questions to confirm you own the  account.

Use these tips to answer as best you can. 

1. You may be asked:

   • To enter an email address or phone number where you can be reached.

   • To enter a code sent to your email address or phone number. This code helps make sure you can access that email address or phone number.

• You might have been sent a Google prompt instead.

• If a text message with a verification code was sent to your phone, make sure your service plan and mobile device supports text message delivery. 

  • Delivery speed and availability may vary by location and service provider. 

• Make sure you have adequate internet connection when you try to get your codes.

• If you get a voice call with a verification code sent to your phone, you get a voicemail if: 

  • You can’t answer the call.

  • You don’t have an adequate internet connection.

Tip: If you requested multiple verification codes, only the newest one works.
