Is writing passwords down on paper really that bad?
It is less bad than reusing weak passwords: a note at home is safe from hackers on the other side of the world. But paper does not scale, sync, or back itself up, and it gets lost. For everything except a few emergency codes, a password manager is the better vault.
The classic advice "never write a password down" deserves nuance. The biggest threat to your accounts is online: criminals mass-testing leaked passwords. A note in a drawer at home is unreachable to them. For someone less comfortable with technology, a notebook with strong, unique passwords is honestly safer than the same easy password everywhere.
But paper has real limits: it does not autofill (and autofill is precisely what protects you against fake websites), it does not sync to your phone, it makes no backups of itself, and anyone who finds it can read it. Loss or fire means everything is gone.
The sensible combination: a password manager for daily work, and paper for the exceptions that should not live in the vault, like the master password itself, the recovery code, and 1Password's Emergency Kit. Those go next to your passport, not under your keyboard.
