2FA

2FA is a form of multi-factor authentication that uses exactly two different factors, most commonly a password plus a code or hardware key. It blocks most credential-stuffing and phishing-based takeovers because a stolen password alone is not enough. Many services now require it for sensitive accounts.

• NordPass → Zero-knowledge password manager with breach monitoring and passkey support. Pair it with MFA; it is step one, not the whole plan.
• YubiKey 5C NFC → Hardware security key supporting FIDO2, U2F, TOTP, and passkeys. Phishing-resistant in a way app codes are not, but buy two; losing your only key locks you out.
