How To Create 2 Factor Authentication
Protect your account with 2-Step Verification
With 2-Step Verification (also known as two-factor authentication), you add an extra layer of security to your account in case your password is stolen. After you set up 2-Step Verification, you'll sign in to your account in two steps using:
- Something you know, like your password
- Something you have, like your phone
Turn on 2-Step Verification
- Open your Google Account.
- In the navigation panel, select Security.
- Under "Signing in to Google," select 2-Step Verification Get started.
- Follow the on-screen steps.
Your account, username@gmail.com, is associated with your work or school. If you can't set up 2-Step Verification, contact your administrator.
Verify it's you with a second step
After you turn on 2-Step Verification, you'll need to complete a second step to verify it's you when you sign in. To help protect your account, Google will request that you complete a specific second step.
Use Google prompts
Important: To use Google prompts, you need an Android phone with updated Google Play services.
We recommend you use Google prompts as your second step. They're easier to enter than a verification code and can help protect against SIM swap and other phone number-based hacks.
To get Google prompts on your Google Account, you need:
Based on the device and location info in the notification, you can:
- Tap Yes to allow sign-in.
- Tap No to block sign-in.
Use other verification methods
You can set up other verification methods in case you:
- Want increased protection against phishing
- Can't get Google prompts
- Lose your phone
Use security keys to increase phishing protection
Use Google Authenticator or other verification code apps
Important: Never give your verification codes to anyone.
You can set up Google Authenticator or another app that creates one-time verification codes when you don't have an internet connection or mobile service.
Enter the verification code on the sign-in screen to help verify it's you.
Use a verification code from a text message or call
Important: Never give your verification codes to anyone.
A 6-digit code may be sent to a number you've previously provided. Codes can be sent in a text message (SMS) or through a voice call, depending on the setting you chose. To verify it's you, enter the code on the sign-in screen.
Tip: Although any form of 2-Step Verification adds account security, verification codes sent by texts or calls can be vulnerable to phone number-based hacks.
Use backup codes
Important: Never give out your backup codes to anyone.
You can print or download a set of 8-digit backup codes to keep in a safe place. Backup codes are helpful if you lose your phone.
Skip a second step on trusted devices
If you don't want to provide a second verification step each time you sign in on your computer or phone, check the box next to "Don't ask again on this computer.
Important: Only check this box on devices you regularly use and don't share with anyone else.
