Add a backup verification method
Choose a backup or alternate method to receive authentication codes. This method will be used if you are unable to receive your authentication code through your primary device.
Select a backup method that is different from your primary method.
If you choose Text
message (SMS) or Voice
delivery (you will receive a phone call), enter the phone number.
You must add a backup device to complete the
Two-Step Verification process. If you aren’t near your backup device, select the
Skip verification check box,

number. Amazon will not initiate a verification of that number.
If you are unable to download an authenticator app, or don't have a second phone number, we recommend using the phone number of a friend, spouse, or other family member.
If you are unable to receive an authentication code through either your primary or backup device, you might need to go through the Account Recovery process in order to regain access to your account. This can take up to 48 hours.
You can make your device a "trusted device," so you don’t have to enter an authentication code every time you try to access your account.
To make your device a trusted device, select Don’t require codes on this device.
