Multi-factor authentication (MFA) or Two-factor Authentication (2FA) is a security feature that requires more than one method of authentication to verify your identify. This strengthens the standard credentials-only authentication by adding extra security for high-risk actions. Bellco’s banking platform supports receiving one-time verification codes via SMS (text message) or voice call. Please note, Bellco will NEVER call you asking for this code. It is recommended to never share your MFA code with anyone.
