I don't know my Verizon voicemail password

If phone is on a Christman account you can put in a ticket asking us to reset your password.  If you manage your own account you can go to their web portal and look for any password links. 

But probably the quickest way is from your phone. 

1. Call *611 (airtime-free) to reach the automated Customer Service menu.
2. When the auto-attendant asks how they can help, say "Change my password"
3. You will receive a text message with instructions.
