🔐 Local password check

Password Strength Checker

Estimate whether a password pattern is weak, fair, strong, or excellent before you move it into a password manager.

No upload The password field is scored in this page only. Omellody does not receive, store, hash, or transmit what you type.

Check a password locally

Privacy note: This tool has no submit button and does not use localStorage. For extra caution, test a similar pattern instead of a live banking or master password.
Use length and uniqueness over predictable swaps like P@ssw0rd!
Compare password managers

Start typing to see the score.

How to use it safely

Type a password or a similar pattern.
Do not include usernames, email addresses, account names, or recovery hints.
Read the score and warnings.
Length, repeated characters, common words, and predictable sequences matter more than one symbol.
Create a unique replacement.
Use a long passphrase or a random password generated by a password manager.

What this checker cannot do

It cannot know if your exact password is already leaked because this page intentionally avoids network lookups. Use a password manager with breach monitoring for real vault audits.

Password strength FAQ

Does the password strength checker upload my password?
No. The checker runs in your browser with local JavaScript. It does not submit, store, log, or transmit the password you type.
Can this tool tell me if a password has appeared in a breach?
No. This page does not contact breach databases because that would require a network lookup. Use a reputable password manager's breach monitoring or a privacy-preserving breach check for that job.
What makes a strong password in 2026?
Length, uniqueness, and unpredictability matter most. A long passphrase or a randomly generated password stored in a password manager is stronger than short passwords with predictable symbol substitutions.
Should I type my real master password here?
You can, because the tool is local-only, but you do not need to. If you are uncomfortable, test a similar pattern instead and use your password manager's built-in health check for real vault items.
