I cannot log in to my account using PuTTY
I tried to set up and log in to my website via SSH using PuTTY following your tutorial procedures. (I thought I had to log in via SSH.) But I do not know what the passphrase for key "imported-openssh-key" is. From then on, I cannot log in to my account using PuTTY. What should I do if I log in to my account normally?
