Coinbase provides several options for generating 2-factor authentication (2FA) codes:
- Authenticator (more secure)
- SMS/Text codes (less secure)
This page describes the setup process for each 2FA type.
Authenticator
Google Authenticator or similar authenticator apps provide the most secure configuration for 2FA. These do not require phone reception or internet access once set up. Authenticator is not associated with your phone number (although we do require a phone number to be registered to buy or sell digital currency) so is not susceptible to phone number porting attacks.

SMS/Text
If you verify a phone number via text message without installing any Authy apps, you will automatically receive 2FA codes via SMS text message.
Note: If you have any Authy apps installed or Authenticator registered, you'll no longer be able to receive SMS codes. Please refer to
2-Factor Authentication Troubleshooting if you have lost your Authenticator or Authy app.
Landlines/VOIP
It is not possible to receive 2FA codes delivered to a landline phone number by voice call.
