Source tree fix for git Password authentication is temporarily disabled as part of a brownout. Please use a personal access token instead

1 - Generate a new token from git dev settings

2 - In SourceTree, you just need to change your repository settings there:

3 - Change the URL/Path with the new format:

https://<USERNAME>:<TOKEN>@<GIT_URL>.git

4 - Press OK and it is good now!

in source tree > open repo settings > remotes tab > edit the remote "URL/path" to be

https://{personal-access-token>@github.com}/{<my-repo>}.git>

then save and try to push

i did like @heratyian answer and works fine.

Step by step using the terminal and github

1. Remove repo

git remote remove origin

2. Generate personal access token https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token

3. Add remote back using personal access token

Remember to replace <personal-access-token> and <my-repo> with your credentials.

git remote add origin https://<personal-access-token>@github.com/<my-repo>.git>

If on Windows, open the Credentials Manager and delete your github credentials if any.

If on macOS, open the Keychain Access app and delete your github credentials if any.

Then, get a Personal Access Token by following the guide here https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token

Then push your code as normal and when asked enter your newly generated personal access token.

I went: Tools>Options>Authentication. Edited my account.

I changed Authentication from Basic to OAuth. And now the brownout no longer affects me.

After setting up my PAT and setting up my account in Sourcetree menu -> Preferences -> Accounts, I still got the brownout error. Adding your account in SourceTree seems to prompt for a password upon opening.

I set up git to cache my credentials: https://docs.github.com/en/get-started/getting-started-with-git/caching-your-github-credentials-in-git

Then in SourceTree I re-cloned my repo. Got prompted for a password - entered my PAT. Now it's working fine.

I have solved the issue, just to ad up on woland's comment.

First add a personal access token then add it in your credentials Second add a remote by clicking the gear settings then add a remote Add the remote of your repository then link it with your account that has logged personal access token. lastly fetch to that remote origin.
