SourceTree gives me a login Error when I try to add my gitlab account

Question

I would like to add my gitlab account to sourcetree. Inside Preferences -> Accounts, I tried the 'add' button

host: GitLab.com
Auth type: greyed out
username xxxxxx
password: xxxxxx
protocol: https

when I go to save. I get a pop up screen that says: "We couldn't connect to GitLab with your (XXXXXX) credentials. Check your username and try the password again."

I've double checked both username and password.

Solution 1

Someone on the GitLab forum had a similar issue recently, and they documented the steps to solve it:

I eventually noticed that for github and bitbucket the credentials are through "Oauth", and for GitLab "Personal access token". I had generated yesterday a toke, but hadn't used anywhere.

Steps to add a repo from GitLab on SourceTree:

1. On your browser, go to your account and > User settings > Personal Access Tokens (https://gitlab.com/profile/personal_access_tokens)
2. Generate and copy the token

3. On Sourcetree,

   a) leave https as preferred protocol

   b) click on Refresh Personal Access Token

   c) type your username

   d) use the copied token as password

I am adding some advantage to @David's answer. Follow whatever steps he has mentioned but remember to select all scopes while creating a personal token.
