VRC Password Lock (Free!)
As of 8/9/24 this product is considered deprecated and doesn't include support. The product remains available for download, but it might not be fixed if something breaks.
The main purpose of this system is to provide security against modified clients that steal avatars in-game, making it useless to anyone who doesn't know the password, but it also has other uses, such as limiting an avatar to certain users or making previews for people that know the password.
Note that this system does not prevent or protect against ripping. It was originally made for clients that forced avatars directly into one's account. This lock is very simple and definitely not foolproof. If safety is a priority for you here are other systems I'd recommend instead:

Since I made this, other free systems have come out, you can check them out if you're looking for other features:

You only need to unlock the avatar the first time it's loaded!
To use the Password Lock, just drag the script found in the folder "Password Lock - GabSith" onto your avatar, then in the inspector type your password and hit "Apply Password"
You can also optionally disable toggles, and change the submenu where the lock is
You can open the "Extras" fold-out to change write defaults settings, toggle whether the script should make backups of the controller it modifies (on by default), remove all components or individual parts, and some other things!
Feel free to use, modify and redistribute as needed. Commercial use is allowed.
Notes:
-When making a quest compatible avatar that's password-protected, make sure both the pc and quest version have the same password, otherwise only one of them will unlock, which could cause discrepancies
