cannot login with username/password it always redirects to SSO

[jasom]

I'm not using SSO, I can login with other matrix clients without SSO. However when I try with weechat-matrix it requests SSO:

I'm having the same problem, but only with matrix.org homeserver, so this sounds like a limitation of matrix.org itself, which requires SSO ?

This is the ironic screen I'm shown when trying to follow the weechat-matrix instructions:

                                                   Choose identity provider
                    Log in to matrix.org

Note how "decentralized communication" and that list of identity providers are in disagreement...

The matrix-weechat instructions were:

16:07:51  -- | matrix: The server requested a single sign-on, please open this URL in your browser. Note
             | that the browser needs to run on the same host as Weechat.

             | 0.0.1:58683
16:07:51 =!= | matrix: Error decoding SSO login message from child process:

The last line is what happens after killing the browser (links) I used to follow the instructions

Info from #matrix IRC channel on libera.chat:

6:11:35         ilmari | strk: https://matrix-client.matrix.org/_matrix/client/v3/login returns sso,
                        | token, password and appservice flows
16:12:08         ilmari | in that order. maybe weechat only looks at the first one?

[strk]

The code seems to ASSUME server requires SSO if it gets a redirectURL typed response

[strk]

It looks like while this fails with weechat-python 0.2.0-2 as packaged by Debian GNU/Linux 11 (bullseye), it is fixed by installing weechat-matrix from current master branch as of 989708d1fa8fcee6d5bbb4c19a7d66f14d84fd5b
