On Windows, in contrast to Linux and macOS, for a long time SSH was only available through 3rd-party applications. With Windows 10 this eventually changed and for a while it has now been shipped with OpenSSH built in.
For many people this created the situation that they had to work with two SSH key agents, when using private key authentication. The most common use-cases for the latter are probably using SSH when working with Git (incl. clients like TortoiseGit, VS Code, etc.), and for remote access to Linux/UNIX systems.
The good news is that it is finally possible to integrate PuTTY’s key agent (pageant) with OpenSSH and by that having only to type the passphrase once.
When installing Git for Windows, you will have to enable the use of “External OpenSSH” for authentication, which as of this writing is not the default setting.
The setup details can be found in this blog.
