Bitbucket – when you suddenly cannot login with git username/password from git any more

Posted by jpluimers on 2017/05/16

When logging in using the Web UI with a username

When logging in using the Web UI with a username

As of a few days, I was getting this error in my SourceTree output when pushing to git :

remote: Invalid username or password. If you log in via a third party service you must ensure you have an account password set in your account profile.

I think this is at least related to a change Bitbucket made 2 years ago for their site logon:

You can no longer log in with a username. Use your Atlassian account email address instead.

Source: Bitbucket

Pushing to bitbucket with cached credentials from SourceTree has worked for months. One thing that was different now (and should have given me a clue) the broken [WayBack] broken Git Credentials Manager popup showed but should not have.

When you get this credential manager you have to escape it as otherwise you will get an “Empty password” error.

Initially I blamed the error on the SourceTree 2.x upgrade I did last week. Unlike previous upgrades, this one had kept the old version (in my case 1.9.13.7) around and after a few clicks (skipping the “go to download page” prompt forever) and closing SourceTree 2.0, I fas able to start SourceTree 1.9 again.

SourceTree 1.9 had the same problem which meant it was either git itself, or the Bitbucket back-end.

To prove it was the Bitbucket back-end, I did everything An example of this is in the output below.

Solving the problem

What helped were these steps:

  1. Change the git repository from https://jeroenp@bitbucket.org/jeroenp/fastmm.git to
    https://bitbucket.org/jeroenp/fastmm.git
  2. Change the “username” field for the bitbucket repository to be my email address.
  3. Remove any bitbucket cached credentials from SourceTree.
  4. Restart SourceTree.
  5. Performing a push
  6. Cancel the Git Credential Manager popup
  7. Use my primary bitbucket email address for logon

Now SourceTree happily cached my credentials.

I’ve used this to scan the git config files for ones starting with a username:

grep -inSwl jeroenp@bitbucket config

Notes:

From the console

Reproduction of the issue:

C:\Users\jeroenp\Versioned\FastMM>git --version
git version 2.12.2.windows.1

C:\Users\jeroenp\Versioned\FastMM>git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags --set-upstream bitbucket develop:develop
Pushing to https://jeroenp@bitbucket.org/jeroenp/fastmm.git
Logon failed, use ctrl+c to cancel basic credential prompt.
Password for 'https://jeroenp@bitbucket.org/':
remote: Invalid username or password. If you log in via a third party service you must ensure you have an account password set in your account profile.
fatal: Authentication failed for 'https://jeroenp@bitbucket.org/jeroenp/fastmm.git/'

This has worked for months (after [WayBack] canceling the Git Credentials Manager popup as that has been broken for a very long time and gives you a remote: Empty password).

What helped was this:

C:\Users\jeroenp\Versioned\FastMM>git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags --set-upstream bitbucket develop:develop
Pushing to https://bitbucket.org/jeroenp/fastmm.git
Logon failed, use ctrl+c to cancel basic credential prompt.
