I use BitBucket and had to change my password because it was compromised.
git pull
remote: Invalid username or password. If
I know that this is an old question, but I thought I would provide the solution that worked for me. I signed up for bitbucket using my google account and did not have a password. Turns out the password is my Atlassian account password. If you have an Atlassian account then try this password to see if it works.
