FileVault Encryption question on a MacBook Pro (14-inch, 2021) M1 Pro chip

[iphonefreak450]

I recently had changed my login account password. Do I need to re-encrypt again with FileVault?
Just asking, because I know that the account password is needed in order to decrypt FileVault.

Running MacOS Ventura.

No.

Edit: If you want a more detailed answer, have a look at the platform security.
