My TB updated to 91.8.0 this morning and I was no longer able to send through Gmail. I think there are other steps required, though I don’t know what they might be. Yours is the only comment I’ve seen mentioning the need to step through intermediate versions.
#OPERA MAIL AUTHENTICATION FAILED INSTALL#
I’d actually given up on using Thunderbird for a bit and decided to just try again after a while, in case there was another update or more information.īut, following your instructions to install version 52, then 60, then 78–as soon as I installed 78 and started it, it made me log in and allow one more time, and then started downloading all my messages from the past few weeks.
#OPERA MAIL AUTHENTICATION FAILED PASSWORD#
I had followed other instructions to change each account’s settings and the outgoing server settings, and to allow cookies (and I’d looked for passwords to delete, but found the saved password list empty) but it had not helped. Thank you very, VERY much! That is exactly what I did initially (for some reason I had a fairly old version) and I could not figure out why it was stuck in a loop of making me log in to each gmail account and asking to allow Thunderbird… and then not downloading any messages (though gmail obviously knew about it, as it sent a security alert each time). > However, if you install and start Thunderbird 91 out of the blue, trouble is expected to occur because the version is too open. Note: if you are using add-ons, “legacy add-ons” will no longer be available due to the Thunderbird upgrade. 91 is installed, and then the “sequential updating” must be performed. Past versions of Thunderbird can be downloaded fromįirst, install Ver. If the update is done correctly, the password should be “migrated from the old DB to the new DB”, but if that fails, the password cannot be read from the password manager (i.e., authentication fails), and the password cannot be saved even if it is entered. The database of security certificates changed from cert8.db to cert9.db.
The database of keys required for encryption/decryption of passwords, etc. The security database was changed in Ver.52 > Ver.60. This is because profile specification changes along the way may not work.
#OPERA MAIL AUTHENTICATION FAILED UPGRADE#
It is important that the upgrade be done in stages and in sequence. Then go up three levels (Roaming folder) and copy the entire Thunderbird folder and paste it somewhere else. In Thunderbird, open Help > Troubleshooting Information and clickĪpplication Basic Information > Profile Folder: “Open Folder” will open the profile folder in use. However, if you install and start Thunderbird 91 out of the blue, trouble is expected to occur because the version is too open. In older versions, the authentication method is “Normal Password Authentication” and the application password must be issued on the Google Account side. Google’s 2-step authentication, “OAuth2” supported by older versions of Thunderbird, is not compatible with the current Google.
In view of the latest security measures, I strongly recommend that you migrate to the latest version of Thunderbird 91. In short, I believe that Gmail will no longer be available in versions older than Thunderbird 68. Less secure apps & your Google Account – Google Account Help Google will end support for insecure apps (e.g., older versions of Thunderbird) on May 30 of this year.
Is that correct? Or will all Thunderbird users have to upgrade to version 91 in order to make Gmail work? Just as a point of clarification, older thunderbird versions eg from 36 to 78, already have OAuth 2.0 so they won’t need to do anything.
