Fix the weak spots before saving it to a manager or, worse, reusing it somewhere else. ## Test Password Strength Before You Reuse It Weak passwords are still one of the most common ways accounts get compromised. This checker gives you a quick local estimate based on length and complexity, so you can fix a weak draft right away rather than finding out the hard way. ## How to use the Password Strength Checker 1. Type a password: enter the password you want to assess; the check runs locally in your browser. 2. Review the result: check the strength rating, length, character mix, and estimated crack time. 3. Fix weak points: add length and variety or replace predictable words and patterns. 4. Test again: confirm the revised password produces a stronger result before saving it in your password manager. ## How To Improve Password Strength - Aim for at least 12 characters. - Mix uppercase, lowercase, numbers, and symbols together. - Steer clear of personal info and predictable patterns. - Give every account its own unique password. For the best security hygiene, pair strong passwords with a reputable password manager and MFA. ## Related writing tools - Full guide article for this tool - Real-Time Character Counter – No Limit - AI Prompt Token Counter - Word & Reading Time Counter ## Frequently Asked Questions ### Does this checker upload my password?
