Describe the problem

I want to enable Multi-Factor Authentication using the Microsoft Authenticator app. After scanning the QR code, I enter the verification code generated by Microsoft Authenticator, but the system prompts: Error: Invalid verification code. Please try again. I have checked the key displayed on the page, and it appears to be incorrect.

Steps to reproduce

1. Click Set up app authentication

2. Scan the QR code and enter the verification code from Microsoft Authenticator

3. The system prompts: Error: Invalid verification code. Please try again.

4. It seems that the displayed key is incorrect.
