Multi-Factor Authentication (MFA) is required for all Merchant Manager users starting October 26, 2026. If you no longer have access to enter your MFA security code because your phone is lost, stolen, or destroyed, or your security key (such as a YubiKey) is lost or damaged, your user administrator can remove MFA from your login so you can set it up again. If you cannot reach a user administrator, contact Qualpay Support. After MFA is removed, set up MFA again the next time you sign in.
