Thunderbird already has the support for ClientID, a Transparent 2FA mechanism, but it currently requires enabling this feature using the Config Editor... manually. This feature request is for having Thunderbird/K9-Mail automatically prompt the user to use CID (ClientID) two factor authentication when the mail server advertises support for CLIENTID. And if the user selects "Yes" to enabling ClientID support for the email account, the relevant "clientidEnabled" entries (in Config Editor) are set to "true" automatically. Now that more and more email platforms are supporting CLIENTID, the sooner end users or customers can be protected with a Transparent 2FA the better. Especially for those operators who are not able or interested in implementing a form of OAuth. Two Factor authentication/identification is best used when it is as transparent to the end user as possible. And if they are using an email account at a provider that offers it, this trust factor helps both parties. ps. It will also be great if K-9 Mail also has ClientID support!
