if by all you mean the closed source ones where they probably don't even encrypt your passwords, sure
but open source ones (bitwarden) are really good and have a clear track record, you can even verify they encrypt everything by checking the source code.
If you wanna go ultra paranoid, however, you can also use something like keepassxc, where not only it gets encrypted, but it stays on your device.
