I found this solution on Chris Hart’s website. Thanks a lot for that! Just adding this to my own “docs base” for personal future reference.
Working with Linux/UNIX machines, I rely a lot on SSH. Thus, not having to type passwords each time I open a new session is a great plus. Achieving this on Linux systems is trivial, since you have the ssh-copy-id command at hand. But, on Windows, that’s missing. Luckily, there is a (logical) way around that, instead of adding keys by hand in the remote server’s authorized_keys file (like I used to do). Below you can see how a new RSA key is generated and then copied to the remote host using a one-liner:
PS C:\Users\drago> ssh-keygen.exe -t rsa Enter file in which to save the key (C:\Users\drago/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in C:\Users\drago/.ssh/id_rsa. Your public key has been saved in C:\Users\drago/.ssh/id_rsa.pub. The key fingerprint is: SHA256:9IHYvsX6pbpS9Fwuq3j648ceNN7pH5MFEt8n0y9O6Jk drago@DESKTOP-KDTKFHA The key's randomart image is: +---[RSA 2048]----+ | . | | o . o o | | . + . . = +| | o.o ..o +o| | .So*o. o o| | .*++.* + | | .o.ooE = | | ..o.+= o | | o**B+ ... | +----[SHA256]-----+
Once the key has been generated, copy it to the remote server. Use your current credentials (user@server). You will be asked to type the password once.
PS C:\Users\drago> type $env:USERPROFILE\.ssh\id_rsa.pub | ssh user@myserver "cat >> .ssh/authorized_keys" user@myserver's password:
And that’s it. Now, each time you ssh to that server (using the specified account), you will be directly logged in, without any other password prompts.
