About Password Generator & Strength Checker
Good credentials must resist guessing without becoming impossible to use. The generator supports conventional character-based passwords and word-based passphrases, including minimum character requirements, ambiguous-character exclusions and batches of independent results. Generation happens only when requested, so experimenting with settings never silently replaces a secret you intended to keep.
The separate strength checker uses pattern-aware analysis to identify predictable sequences, common constructions and other weaknesses that a character count alone misses. Entropy and crack-time figures are estimates rather than promises, but they provide useful context for comparing choices. All generation and evaluation is performed locally in the browser.
