Password Manager vs Password Generator: You Need Both
They look interchangeable but solve different problems. Here is the division of labour that keeps accounts safe.

Ask the internet "password manager or password generator?" and you get tribal answers. The truthful answer is that they are complementary tools that do not overlap. Skimping on either leaves a gap.
What each one does
| Password manager | Password generator | |
|---|---|---|
| Job | Stores and fills passwords | Creates random passwords |
| Stores data? | Yes — encrypted vault | No — outputs, forgets |
| Solves | Remembering 100 passwords | Creating strong unique ones |
| Risk | Vault compromise (rare) | None — stateless |
The division of labour
The generator creates; the manager remembers. One without the other collapses into the same old trap: you either reuse weak passwords you can remember (no generator) or you create strong ones and write them in a notes app (no manager).
The workflow that works
- Generate a 20-character random password with the generator.
- Save it in the password manager, attached to the right account.
- Let the manager autofill it wherever you sign in.
- For the manager's own master password, use a long phrase — 6+ words, only in your head.
That is the whole system. Each account gets a unique strong password; you memorise exactly one thing.
When to skip the manager
Some users prefer generated passwords for sensitive one-off sessions — like kiosks or borrowed machines — where storing a password would itself be risky. Generate per session, use, and forget. The generator shines here precisely because it is stateless.
Whatever you use, turn on two-factor authentication on the accounts that offer it. A strong password plus 2FA is the current realistic definition of "secure".
Is a password manager a single point of failure?
The vault is encrypted with your master password, which never leaves your device. Even if the manager's servers leak, attackers get encrypted blobs they cannot open.
