+# Personal Access Tokens
+## Assumptions 
+* [Git installed](https://git-scm.com/downloads)
+* [Skynet / Forgejo account](https://forgejo.skynet.ie/user/login)
+
+### Why
+The usual way of authentication when working with remote git repositories
+is SSH, unfortunately we aren't able to do that with our git server. You could use username and password
+however that is less secure and inconvenient, personal access tokens on the other hand are a more convenient and secure alternative.
+
+Personal access tokens make it so you don't have to use username / password
+to authenticate, you can authenticate **once** when **cloning** and that's it.
+### How
+Go to [this page and click generate token](https://forgejo.skynet.ie/user/settings/applications)  
+Give it a name and select read and write for repository permissions  
+Copy it once its generated  
+
+**Note : Do not share your access token with anyone, if its compromised delete it, this can be done easily
+[here](https://forgejo.skynet.ie/user/settings/applications) and prevents it from being used.**
+
+When cloning a repository, use the token like so..  
+```git clone https://<token>@forgejo.skynet.ie/<repo>```
+
+You now should be able to push to the repository without being prompted for username / password.
