How to customize a password (without breaking it)
Colors, logos, sizes — what Password Generator lets you change, and what you should leave alone. 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.
Use the tool: Password Generator — Free, no account required, no watermark.
What you can customize in Password Generator
Password Generator exposes the options that matter without overwhelming you with the ones that don't:
- Size — pick the smallest size that still scans reliably for your use case
- Color — foreground and background. Keep contrast high; aesthetics shouldn't fight readability
- Margin / "quiet zone" — the empty border around the password. Don't skip this; scanners need it
- Logo overlay — embed a brand image in the middle. Works because of built-in redundancy in the encoding
What you shouldn't change
- The error-correction level (raise it, don't lower it)
- The encoding format (let Password Generator pick the best one for your input)
- The aspect ratio (always square — non-square passwords are unreadable)
