An “ID.me phone number” is a secure and efficient way to verify your identity online. When you create an ID.me account, you can choose to link your phone number to the account. This allows you to use your phone to receive one-time passcodes (OTPs) for two-factor authentication (2FA) and to log in to your account if you have forgotten your password.
Using an ID.me phone number is more secure than using a traditional password, as it is much harder for hackers to gain access to your phone number than it is to guess your password. It is also more convenient, as you do not need to remember a separate password for your ID.me account.
