Fatal: Authentication failed (on git push)


Lost authentication from BitBucket resulting in invalid credentials. Pushing to BitBucket and received this response:

remote: Invalid credentials
fatal: Authentication failed for **repo**


  1. Go to https://bitbucket.org/account/settings/app-passwords/ and create a new app password

  2. Tick all the permissions required, copy the password

In terminal:

On an already-cloned project:

git remote set-url origin https://bitbucket-username:app-password@bitbucket.org/repo-name.git

To clone a new project:

git clone https://bitbucket-username:app-password@bitbucket.org/repo-name.git

Why is it happening?

Beginning March 1, 2022, you will no longer be able to use your Atlassian account password when using Basic authentication with the Bitbucket Cloud REST API or Git over HTTPS.
