We know there's a lot to learn and read about all that Clerk can do. Here are some of the most frequently asked questions.

SMS verification, or SMS two-factor authentication (2FA) and SMS one-time password (OTP), allows users to verify their identities with a code that is sent to them via text message.

This is real mobile number that is associated with a physical sim card. Highly secure services such as Banks, Facebook, LinkedIn will only send a verification sms to a non virtual number.

Clerk allows you to share 2FA, MFA, OTP verification codes with your entire team. Just connect your existing number or get a new one and start receiving codes today. Clerk is powered by T-mobile, AT&T, and Verizion and will work with ALL online services.

If you are unable to receive SMS verification codes most likely the service you are enabling MFA on does not accept VOIP phone numbers. You will need to request a Clerk non-voip number.

Yes. Most existing internet services such as Google, Apple, and others allow the use of a US based phone number for verification purposes.
