If it's a password, sure, rotating it every once in a while should secure your account if someone has stored a copy of the encrypted (usually hashed) version; that said, rotating passwords is no longer a recommended practice, and second, it's more important for encrypted data, like hard drives, online e2e-encrypted chats, internet usage, images/files, etc. You can change the password / key on those too, but if someone already has a copy of the old password encrypted data it may be cracked later on.

In practice this is probsbly reserved for important people I suppose.
