Is it true that OAuth does not work at the moment? I have been trying to use them in the credentials but i keep getting:

Yes, this issue would not be open other wise.

Would it be possible to increase the prority of this issue? Our company will not allow it's use unless we can use secure authentication methods, and this plugin looks great and just what we need.

Sorry to be persistent , is there any news about this? We would very much like to be able to use this plugin. Is there any way we can help? Unfortunately we are do not have experience in jenkins development (only usage), but we are happy to contribute where possible.

At the least, could you update the landing page for this plugin to reflect the fact that it doesn't support OAuth? I worked on this for a long time before finding this ticket. As far as the Jenkins credentials page is concerned, OAuth credentials are the same as other username/password. Putting this in the README would help a lot. Thanks.

 This issue renders the plugin useless. Is there any ETA for this to be implemented

Hey guys, at least mentioning that OAuth doesn't work would be a great help for other developers. I've spent a good couple of hours trying different options and permissions for my Bitbucket OAuth key. Our company uses two factor authentication for normal BB users and it's only after trying an account that didn't have 2 factor auth turned on that I've finally got this plugin working.

Same here, after enabled two factors auth, tried app passwords, won't work either.

Having the same issue.  With SAML/SSO configured, App Passwords do not work.  

Using bitbucket-branch-source-plugin version 2.2.14

OAuth supported long time ago
