I once got locked out of my Veeva Vault account because I couldn't remember who I put as "who was your best friend in kindergarten?" (I had like 8 best friends then!). After putting in a ticket and hearing nothing back I finally braved the phone system and called support line. The rep who unlocked my account and reset my password assigned me 4 different modules of 60-question EACH mandatory training in order to get back into my "dashboard."
