- Is the password generator random enough?
- It uses cryptographically strong randomness in your browser. Choose length and character sets; nothing is uploaded or saved.
- What does the contrast checker test?
- WCAG 2 contrast between foreground and background colors, with AA and AAA pass/fail for normal and large text.
