create new SSH-Key - how to show or change private Key passphrase

Hello,
I use RDM 2026.1.22.0 and used the ssh key generator to generate a SSH key. I pressed th button "generate", than input a passphrase for the private key and then pressed save.
(if a do not enter a passphrase I get a warning after pressing "save")

Now in the next window, I can't find the passphrase. But I am able to enter a new (or the same) passphrase. Apparently this is used if opend in SSH-Key-Agent)

Please direct me to the manual or explain the intend of usage. For me, the feature doesn't work the way I'd expect it to. I expext a password vault to save all relevant keys, passwords and passphases for me.

Regards Konrad
