Murena Mail password overwritten by Account manager password does not work with MFA

• /e/OS version: 2.9
• Mail version: 6.711-2
• Device model(s): FP3
• Impacted Application: /e/OS Mail

The problem

Since v2.9, Murena mail account is automatically set in Mail. Furthermore, the password is regularly overwritten with Murena account's password given in account manager.

Well it seems to be a good idea, except when 2FA is activated. With 2FA activated, you have to use an application password generated in https://murena.io/settings/user/security to set Murena account in Account manager.

Then this password is used to set Murena email account in Mail app, but that's not the one needed to access emails.

Even if you correct the password in Mail app, it's eventually replaced after few minutes.

Steps to reproduce

1. Have an Murena account with 2FA activated in https://murena.io/settings/user/security
2. Generate an application password in https://murena.io/settings/user/security to add the Murena account in /e/OS 2.9 Account manager
3. Try to fetch your Murena emails in Mail app
4. It does not work because the main Murena password needed to access Murena emails is overwritten by the application password given in Account manager
