Frequently asked questions
Is Password Strength Analyzer free to use?
Yes. Password Strength Analyzer is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Password Strength Analyzer upload your text to a server?
No. Password Strength Analyzer processes your text inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a limit on how much input I can use?
Password Strength Analyzer handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use Password Strength Analyzer?
No installation is needed. Password Strength Analyzer runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Password Strength Analyzer on a phone or tablet?
Yes. The Password Strength Analyzer interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your text when I close the tab?
It is discarded. Password Strength Analyzer keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
