🔐 SecTools

Practical Security for Everyday Life

81% of data breaches involve weak or reused passwords (Verizon DBIR 2025). The single most impactful security action you can take is using a password manager with unique, randomly generated passwords for every account. A 20-character random password from this generator would take billions of years to brute-force, while "Password123!" would take milliseconds.

JWTs (JSON Web Tokens) power most modern authentication — when you log into an app, you get a JWT that proves who you are. The payload is just Base64-encoded JSON, not encrypted. Never store sensitive data in a JWT payload unless it's also encrypted (JWE). You can decode any JWT with this tool to see what information about you is being transmitted.

• Use a password manager (Bitwarden, 1Password, or iCloud Keychain) — one strong master password is easier than 100 weak ones
• Enable 2FA everywhere — you're 99% less likely to be hacked with two-factor authentication enabled
