[Dovecot] Disable IMAP for ONE user only

[SIW]

I'm beginning to wonder if I am going about this all wrong :-)

Would it not be easier/better to leave all IMAP/SMTP access in place 
(for all users) and then just use "one time throw away passwords" for 
logging in from an internet cafe with Roundcube?

Can this be done? So after you login it just deletes the password you 
have logged in with. Can you have one username with many (throw away) 
passwords? But keep one password that is used for IMAP/Thunderbird as 
you don't want that password being deleted/removed from the system!
