Remembering (and inevitably) forgetting passwords for all your different accounts is inconvenient, frustrating, and arguably less secure than a randomly generated password unique to each account.

Additionally, it can be tempting to reuse passwords for multiple accounts, which is trouble when a less-than-reputable service that you used that password on is breached, since that password wasn’t unique.

If you use an open-source, tried and true password manager (Bitwarden, Vaultwarden, KeePassXC) and keep a passphrase unique to that password manager only, you avoid the problems above which are way more likely to occur than Bitwarden passwords getting breached in plaintext, or a security vulnerability to the KeePass database.

Plus, most password managers offer support for passkeys, which are easier to register/use than passwords. They usually only require a “verify with passkey” button on a given website.

Bottom line, password managers are probably (definitely) more secure than any other reasonable solution that anyone has come up with.
