I’m trying to remove my old github ssh key according to this post. Running this command

I have a mac (Catalina) I’ve been SSHing into for a long time with MobaXterm, and am now trying to SSH in from powershell and another mac. On both when I put in my password it just come back asking for the password again. (I know the password is right as that is what I use in MobaXterm). The only possible thing I can see is that in MobaXterm I’m using an SSH-browsewr type of “SFTP protocol”.
