Security keys can be used with 2-Step Verification to help you keep hackers out of your Google Account.
Important: If you’re a journalist, activist, or someone else at risk of targeted online attacks, learn about the Advanced Protection Program.
Step 1: Get your keys
- Buy Titan Security Keys from the Google Store
- Order a compatible security key from a retailer you trust
Step 2: Add a key to your account
- Open a compatible browser, like Chrome, FireFox, or Safari (13.0.4 or higher).
- Enroll your security key. You might need to sign in.
Step 3: Sign in with your key
Security keys are a more secure second step. If you have other second steps set up, use your security key to sign in whenever possible. If a security key doesn't work on your device or browser, you might see an option to sign in with a code or prompt instead.
- On your computer, open a compatible browser like Chrome, Firefox, Edge, or Opera.
- Sign in to your Google Account.
- Your device will detect that your account has a security key.
- Connect your key to the USB port in your computer.
- If you find a message from "Google Play services," clickOK.
- If not, move on to step 4.
- Activate your key:
- If your key has a gold disc: Tap it.
- If your key has a gold tip: Tap and then press it.
- If your key has a button: Press it.
- If your key has none of these features: You may need to remove and reinsert it. This type of key turns off after each use.
Tip: You can use your key each time you sign in or skip using it on devices you trust.
If you receive the error, “You need to register this Security Key to your Google Account before you can use it to sign in”:
- Attempt to sign in with a different account.
- Update your Google Play service.
- To add the account in question, try to sign in again.
Tip: You’ll be asked for your security key or another second step any time you sign in from a new computer or device.
Organize your security keys
You can manage your security keys under your 2-Step Verification settings. There, you’ll find a list of the keys you’ve added, from the most recent to the oldest. You’ll also find more info such as the key's name, the date it was added, and the date it was last used. The key’s name defaults to “Security Key” unless you choose a custom name.
You also have the option to edit each security key’s name or to delete it.
Next to each security key, click on the pencil icon 
to edit its name. This means that if you have multiple security keys, you can better identify them with a custom name.
Next to a security key, click on the trash bin icon 
to remove it so that it’s no longer connected to your Google Account. When you remove your security key, you’ll be asked for confirmation. You may also need to sign in to your Google Account again.
If you can’t use your security key, you can generate a security code for 2-Step Verification:
- On a device signed into your account, go to g.co/sc.
- Follow the on-screen instructions.
Reset your locked security key
Some security keys need extra verification, like a PIN.
If your security key is locked due to multiple incorrect PIN entries and must be reset:
- On your computer, open Chrome

Note: 2-Step Verification requires an extra step to prove you own an account. Because of this added security, it can take up to 3-5 business days for Google to make sure it’s you trying to sign in.
- Follow the steps to recover your account. You'll be asked some questions to confirm it's your account.
- Use these tips to answer as best you can.
