Login fails with "Invalid credentials" although myAudi credentials work in app and browser

[tux1980]

Description & ## Environment

Home Assistant version:
Core 2026.7.2
Supervisor 2026.06.2
Operating System 18.1
Frontend 20260624.3

Audi Connect integration version: V 2.2.0

Browser login on my.audi.com working: Yes, is working without problems.

Audi Connect integration version
Vehicle type/model/year
Browser login on my.audi.com working: Yes/No

The Audi Connect integration no longer accepts my login credentials. Home Assistant shows the error:

Invalid credentials

However, the same credentials work correctly in the official myAudi app. I also changed the password in myAudi and verified that I can still log in successfully with the new password outside of Home Assistant.

The integration still rejects the login with the same "Invalid credentials" message.

What I tried

• Verified the username and password in the official myAudi app
• Changed the myAudi password
• Logged in again successfully in the official myAudi app
• Retried the Audi Connect integration setup in Home Assistant
• Used region DE
• Used a 15 minute polling interval
• Restarted Home Assistant
• Tried re-entering the credentials several times

The issue persists.

Expected behavior

The integration should accept the valid myAudi credentials and complete the setup/login process.

Actual behavior

The integration immediately fails with:

Invalid credentials

Screenshot

The setup dialog shows the message "Ungültige Anmeldeinformationen" / "Invalid credentials" although the credentials are valid.

Additional context

This does not look like a normal wrong-password issue because the same login works in the official myAudi app. It may be related to a recent Audi/CARIAD login or token endpoint change.

Please let me know if there is anything specific I should test, such as a different API level, additional debug logging, or a specific branch/version.
