Static vs dynamic passwords — picking the right type
When to use a one-shot static password and when to use a dynamic one. Trade-offs, plain and clear. Browser-based, free, no signup, runs entirely on your device.
Generating a password sounds like it should require an app — and historically it did. Password Generator runs the same thing in your browser tab, with one tap and no signup.
Run it in your browser: Password Generator — Runs entirely on your device using open web standards.
Static vs dynamic passwords
A static password encodes its content directly. Once generated, it never changes. Pros: works forever, no infrastructure. Cons: can't be updated without re-printing.
A dynamic password encodes a redirect URL to a server you control. The destination can be changed without reissuing the password. Pros: flexible, analytics. Cons: requires a server, depends on its uptime.
How to choose
- One-shot, never changes: static password. Use Password Generator, you're done.
- Will the destination change? Dynamic password. Password Generator generates the encoding; the redirect logic lives elsewhere.
- Need analytics? Dynamic. Static passwords are invisible after they leave your device.
