Problem: When using SSH to connect other server, I don’t want to type passphrase everytime:)
For Windows 10 you need PowerShell to active ssh-agent in order to save passphrase.
Solution: First use Administrator right to open PowerShell (Windows PowerShell).
Then enter below command to active ssh-agent:
local Administrator PowerShell Set-Service ssh-agent -StnartupType Automatic Start-Service ssh-agent Get-Service ssh-agent
Then now you can add the key file (My file store in C:\Users\user.ssh\id_rsa), it will prompt a message to obtain the passphrase.
ssh-add C:\Users\user.ssh\id_rsa (Enter your passphrase)
Eventually, ssh-agent will store your passphrase now. You can also enter
to check out the record.
