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.
