Is it possible to pre-generate usernames/passwords?

[vigilsolace]

I am setting up a vbulletin cloud solution for an organization with a few thousand existing accounts in an alumni database. Is it possible to pre-populate usernames and passwords in vbulletin to match those accounts? So far the only info I've found is this: https://vborg.vbsupport.ru/showthread.php?t=311972&highlight=generate+password

Thanks for any help.
