Why PhrasePocket exists
Strong, memorable passphrases are hard to make well. Online generators require trusting a website with the very phrase you will memorize, and most strength checkers send your input to a server. Users want a trustworthy, offline generator and an honest analyzer.
What PhrasePocket does
- Diceware generator using SecureRandom and curated EFF wordlists
- Configurable word count, separator, capitalization, and appended digit
- Live entropy in bits, plain-language strength, and offline crack-time estimates
- Strength lab: score any candidate locally — the input is never transmitted
- Optional encrypted, biometric-gated drafts store to compare phrases later
- Copy with 30-second auto-clear; FLAG_SECURE on sensitive screens
- Teaching mode explaining entropy and why offline generation matters
- No INTERNET permission at all — fully offline, no account, no subscription
