Security Tools
Generate passwords and passphrases, check strength, encrypt text, and scrub data — privately in your browser.
Handiwork’s security tools help you protect accounts and data without trusting a third-party server. Create long, random passwords and memorable passphrases, estimate password strength, encrypt text with a password, or redact supported identifiers and secrets from text before you share it.
Privacy is the whole point, so these tools run entirely in your browser — nothing you generate, type, or paste is uploaded. Select a tool below to get started.
