Strange experience whenever I log in at mail.yahoo.com

For a year or so, every time I attempt to log in at mail.yahoo.com to check the inbox of my bellsouth email address, it forces me to create a new password and new 'security' questions and answers, and then finally says something like "Oops -- something went wrong on our end" and proceeds to take me into my inbox anyway That's quite an involved (and apparently useless) process to put someone through just to log in and check their email. Does AT&T or Yahoo have any plan to correct this?
