Comment 1 for bug 1825474

That's just the nature of storing secrets for later use. The only way to store a key in an encrypted form would require the user to then supply a decryption key, probably in the form of a password that would then be handed to a key derivation function. That only slightly moves the goalposts.

I'd expect that you should be able to delete that line or that section of the file to then be prompted for the password when establishing a connection; if so, that's probably the direction to take.

Thanks
