Still fairly new to Dreamhost. Went to login to panel today to check a ticket status, and it said my password had "expired". Do passwords "expire"??
If you set up the multifactor authentication , there is a good chance that it might have expired. You can set it to remember your computer for a week or a month. https://help.dreamhost.com/hc/en-us/articles/216013897-Multifactor-Authentication-overview
