Forgot Vault password

Hello fellow cryprobros. Today I come requesting your help because I am such a dipshit, and closed all my reddit sessions without backing my vault, only to later on realize I could not recall the password.

Is there any way around this? Do my meme team and world cup avatars get lost if I do open another vault? Moons I don't care that much, I could always get more, but the avatars are something I grew fond of and who knows, maybe I can sell for some bucks $ in the not so distant future.

Thanks in advance.
