About Password Strength Checker
Weak passwords are still behind a huge share of account takeovers, yet "strong enough" is hard to judge by eye. This Password Strength Checker scores any password and tells you exactly why it falls short, looking at length, character variety, predictable patterns, repeated sequences, and common dictionary words instead of just counting symbols. The result is honest feedback you can act on rather than a vague green bar.
Type or paste a password and ToolHub by Codaiman evaluates it instantly in your browser, returning a strength rating plus concrete suggestions to improve it. It is free, needs no signup, and nothing you type is stored. Use it to vet your own passwords, set realistic policies for a product, or teach a team what actually makes a credential hard to crack.

FAQ
Does it check if my password was leaked in a breach?
No. It analyzes the structure and entropy of the password itself, not whether it appears in known breach databases. Treat a high score as one signal, not a guarantee.
What makes a password score higher?
Greater length, a mix of upper and lower case, numbers and symbols, and the absence of common words or keyboard patterns all raise the score. Length usually has the biggest impact.
Is my password sent anywhere?
The analysis runs without saving your input, so the password is not stored. Still, never paste a live production password into any tool you do not fully control.
Can I use Password Strength Checker on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
