Can’t receive SMS two-factor authentication (2FA) codes
Most delivery issues are caused by your mobile carrier or personal filtering settings blocking the message.
Common causes
-
Carrier or customer-level SMS filtering/short-code blocking
- Incorrect phone number or country code
- Poor signal, roaming restrictions, or corporate mobile policies
If this happens during first-time login (security setup)
-
Select a different supported 2FA method (e.g., an authenticator app) to complete setup.
If this starts after your first login
-
Contact your organization administrator and ask for a user profile reset so you can re-enroll 2FA. This reset does not delete any robot or sensor data.
