Gitextensions: Git credentials saving.

[takinosaji]

Program asks for login and password every time I query remote repository,

--- GitExtensions2.48.05, Git 2.5.2.windows.1, Microsoft Windows NT 6.3.9600.0

Did you set credential helper?
Settings -> GitExtensions -> SSH -> Configure Git credential helper

[takinosaji]

No i haven't. Do I have to press "Suggest" button? The following pass is proposed:
"...\GitExtensions\GitCredentialWinStore\git-credential-winstore.exe" Is it an assembly which saves credentials?

I've always manually modified my .gitconfig file by hand, as the default values for the credential helper (in my experience) have always been set incorrectly.

Open your local user .gitconfig file (Located here:%UserProfile%\.gitconfig)

Find the [credential] section, and modify it the values below. If your file doesn't have this section, you should be able to directly copy/paste the below configuration.

[credential]
  helper = wincred

Here's a link to the documentation that mentions the wincred helper in-passing: 7.14 Git Tools - Credential Storage

Note: As mentioned in the link above, you can also set it via the command prompt:

git config --global credential.helper wincred

It may be worth mentioning that Github Desktop has always modified this configuration value on my machine (to an erroneous value, no less), which causes the same issue that you're mentioning.
