Does Thunderbird have a bug with Two Step Authentication?

Does Thunderbird know about Two Step Authentication?

I use Does Thunderbird but feel it has a bug with Two Step Authentication. iCloud and Zoho are easy to configure for Two Step Authentication, and both work. Then, for some unknown reason, both have failed.

Do I need a different client?

I really hate needing to log onto my web clients...I have so many email accounts.

Hi ,

Well, this shouldn't happen, as i tested this case on my end (even aftr 2 days) ,  I used the same password (app specific password ). There is no need to reset password again .

But , Thunderbird did prompt me a window as follows:

Check the option "Use Password Manager to remember this password"

Make sure your imap & smtp password are saved in Thunderbird password manager. It worked fine after I check both prompts displayed.
Reason : Once, Thunderbird saves password, prompt will not be displayed again and again
To cross check if both are added :

  • Go to Tools >> Options
  • Select Security >> Saved Passwords

I hope this will resolve your query .

While Setting Up Two Step Verification, Zoho Mail mentions that Standalone applications like Thunderbird do not support Two-factor Authentication. You will need an Application Specific Password to Sign-In within Thunderbird. You can see the screenshot as described below :

Thunderbird Do Not Support Zoho Two Step Authentication

To access in Thunderbird you can generate Application specific code, To create code, follow the steps below :

1. Go to Security SettingsTwo Step Authentication > Click on Manage Application specific Password

2. Now Enter you Device Name & Create New Password.
Generate App Specific Password
Generated Password
While configuring Thunderbird, you have to enter the App specific password (newly generated password)

For More Information on Configuring Thunderbird you can follow this blog :

Note: You do not need to re-login Thunderbird always.
Make sure you remember the password , once generated

This method is tested as displayed in screenshots, I hope it will resolve your issue!

Thanks. But I have doing exactly this process to get my App Specific Password.

It works fine, for a day or so. Then I need to repeat the whole process.

It's like Thunderbird, or my Mac Keychain, fail.
