Overleaf allows git for some users. I have been using emacs and magit with overleaf since some time by providing username-password at each git push or git pull.

What I want

Now I want to configure magit to use username and password from my .authinfo file so that it does not ask me credentials at each push or pull.

What I have

  • Overleaf does not allow ssh public key based authentication right now.
  • Using GNU Emacs 27.1 with Magit 20201218.1819.
  • authinfo entry

machine git.overleaf.com port 443 login [email protected] password eX@mp1e

I have also tried machine https://git.overleaf.com login [email protected] password eX@mp1e

  • magit config
(use-package magit
  :init     
    (setq auth-source-debug 'trivia)
  :config
    (add-hook 'magit-process-find-password-functions 'magit-process-password-auth-source))

What I get

When I try to do a git push, it asks for my username. After I type in my email address (which is my username), it returns this message:

auth-source-search: found 1 results (max 1) matching (:max 1 :host "git.overleaf.com" :user "[email protected]")

And the committed changes get pushed successfully. So I guess this is a minor success since magit is able to lookup the password from the authinfo file when I provide the username.

  • I guess that clarifying if you're able to push and telling how your remotes looks like will help.

  • I'm able to push after I type the username (which is my email). I'm not sure what you mean by 'how your remote looks like'. I want to push without typing the username.

  • About the remotes, I mean the url your remote is using. I guess this probably will work: https://[email protected]/ if your username contains a @ usually replacing it with %40 does the trick from the command line, I never tried with authinfo file. Also there is the git credential system as last resort.

  • There is a closed issue that references the @ related to overleaf. I hope to try your suggestion tomorrow.

I realize this is an old post, but since I solved the username lookup part I want to share in the hopes that someone finds it useful.

I was able to use this question to get the password lookup working using the info from OP. Similarly, I was prompted to enter my username.

I solved the username lookup by adding the following line to ~/.gitconfig:

[url "https://[email protected]"]
    insteadOf = https://gitlab.company.example
