Account & device security
How to protect your accounts and devices without buying things you do not need — two-factor, passkeys, and what modern security software is actually for.
Two-factor authentication: which second factor to choose
Any second factor beats none, but they are not equal. App-based codes are the practical default; a hardware key is the strongest; SMS is the weakest and should be a last resort.
Passkeys vs passwords: when it is worth switching
Passkeys remove the password entirely and cannot be phished, which makes them stronger for most people. Switch your high-value accounts first, and keep a fallback until coverage is complete.
Do you still need antivirus software?
For most people on an up-to-date phone or computer, the built-in protection is enough. Extra security software is worth it for specific situations, not as a default purchase.
