Step by step:
- Download the wincred extension from the following link:
https://github.com/downloads/msysgit/git/git-credential-wincred.zip
- Extract and place the git extension in the following file location:
(32-bit) C:\Program Files\Git\libexec\git-core
(64-bit) C:\Program Files (x86)\libexec\git-core
Note that the following locations may vary across different installations. Modify the file locations accordingly.
- Right click anywhere, select TortoiseGIT > Settings > Git > Credentials.
- In the drop-down menu, check to see if wincred is loaded. To check, there should be three wincred options available.
- If they exist, wincred is installed correctly. Therefore, TortoiseGIT is now able to use wincred.
