Authentication Problems

[Tiziano Mazzoni]

I am quite new about Sourcetree and bitbucket so perhaps my problemis "stupid", in any way when I try to push somthing from sourcetree to bitbucket I have the following error:

git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks push -v --tags origin master:master
remote: Invalid username or password
fatal: Authentication failed for 'https://bitbucket.org/mazzoni1/ecad.git/'

Pushing to https://mazzoni1@bitbucket.org/mazzoni1/ecad.git
Completed with errors, see above.

even if opening the tab Authentication in Tools >> Optionts I have Authentication Ok corrisdponding to my userid, clicking the button Remote, I can access to bitbucket repository (of course I was able to clone the repository from bitbucket to sourcetree)

If someone can help me, it would be very appreciate

Thank you

Hi Tiziano, I have the same problem.. Instead if Bitbucket, I use GitHub.

If I go to Authentication page, I can see "Authentication OK" and there is my correct username, but when I try to clone a repository from GitHub, I have this:

Error: remote: invalid username or password

fatal: Authentication failed for xxxxxxx

Please someone can help me? 

Thank you very much
