Get Started Free →Set up a sane password and two-factor-authentication baseline that's genuinely secure and actually sustainable — a password manager, unique passwords where it counts, and 2FA on what matters. Use when asked to improve my password security, set up a password manager, how do I use 2FA, or make my accounts more secure. Produces a prioritized rollout (secure the crown-jewel accounts first), a password-manager setup, a 2FA plan by method strength, backup-code and recovery safeguards, and a realistic

Perfect security advice that nobody follows is useless. This sets up a baseline that's both strong and livable: a password manager doing the remembering, unique passwords on the accounts that matter most, and 2FA where it counts — rolled out in priority order (email and finances first) so you actually finish instead of giving up at account number three.

Order of operations
2FA by strength: hardware key ≥ authenticator app > SMS (use SMS only if that's all there is). Don't lock yourself out: store backup codes safely · set recovery options · keep a second 2FA method.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 25 cases were attempted. The headline lift of +16 percentage points is the difference between those two pass rates over the 25 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
