The five steps with the biggest payoff
- Turn on two-factor authentication for your main email account.
- Use a password manager and give every important account its own password.
- Switch on automatic updates for your phone, computer and browser.
- Never share OTPs, UPI PINs or your screen with someone who called you.
- Back up important files and test that you can restore them.
How the score works
High-impact habits count three points, medium ones two and good hygiene one, out of 47 in total. The score is the share of points you have; the next step is the unchecked item with the highest weight. It is a self-assessment that helps you prioritise, not an audit of your accounts.

How often should I do a security checkup?
Every six months, and after any big change such as a new phone, a breach notice or a new job.
What is a good security score?
Cover the eight high-impact items first; they are worth about half the points and stop most account takeovers and scams. Above 80% means the important habits are in place.
