Issue with App Password and TOTP Login in EasyRepro

[Ne3maRayan]

Description:

I tested authentication in EasyRepro with the following approaches in our Dynamics 365 environment:

1. App Password

   • I enabled an App Password for my account and attempted to use it with EasyRepro.
   • When entering the App Password, the system returned an “incorrect password” error.
   • After investigation, I confirmed this happens because App Passwords only work with legacy Office 365 authentication (basic auth), which is deprecated and disabled in most tenants.
   • Our tenant enforces modern authentication (OAuth + MFA), so App Passwords are no longer accepted by Dynamics 365.

2. TOTP (Authenticator code)

   • I tested using a TOTP secret in code to generate runtime 6-digit codes.
   • Result: Login still prompted for push notification approval, as expected.
   • Root cause: Our tenant enforces strong MFA policies, where push notifications override TOTP as the primary factor. Even if a TOTP code is generated, push approval is still required.

Impact:

• App Password and TOTP cannot be used for automated login in our environment.
• We currently can only run EasyRepro via interactive login with MFA or via Client ID + Secret (if supported in newer EasyRepro versions).

Request:

• Guidance on best practices for automated login in tenants enforcing modern MFA policies.
• Confirmation if EasyRepro supports Client ID + Secret login in a version compatible with our setup.
