Question: I am using Git to clone my repository in Google Colab workspace then when I try to push changes to my repository, it tells me that access is denied. It doesn't even ask me for my username and password. I have been unsuccessful trying through SSH too. 

May I know if there are any methods by which I can save the manipulated data processed in Google Colab for later use?

Answer: 
If the remote repo URL is an https one, and Git does not ask you for credentials, check your credential helper:

```
git config credential.helper

```

For instance, on [Google Cloud](https://cloud.google.com/source-repositories/docs/adding-repositories-as-remotes), that would be `gcloud.cmd` or `gcloud.sh`.  

That helper might have cached the wrong credentials (username/password)
Have a look [here](https://towardsdatascience.com/kaggle-on-google-colab-easiest-way-to-transfer-datasets-and-remote-bash-e54c64054faa). You can get access to full SSH terminal from Colab instance using Clouderizer. From there you can check in your code changes to git repositary as many times you wish.
