- ✓Use a unique, long passphrase for every important service (banking, email, primary messaging).
- ✓Store all credentials in a reputable password manager so you never have to remember dozens of complex strings.
- ✓Enable Two-Factor Authentication (2FA) everywhere, prioritizing Authenticator Apps over SMS OTPs where supported.
