agreed, if I didn't trust the encryption, I would not use it. I am fine with bitwarden hosting my encrypted passwords, the store is accessible locally on each device, and I can self host with vaultwarden if bitwarden pull the free service. The features in bitwarden are good and sufficient, less awkward than alternatives I have tried.

As someone posted above, someone obtaining access to your encrypted data might lead to an issue in the future:
