Password attacks try to guess, steal, reuse, intercept, or trick you into revealing a password. The biggest real-world risks are reused passwords, phishing pages, infostealer malware, password spraying, credential stuffing, and fake MFA prompts. A strong password helps, but unique passwords and MFA matter more.
How do you stop password attacks?
- Use a password manager and unique passwords everywhere.
- Enable MFA/passkeys on email, banking, and work accounts.
- Do not approve unexpected MFA prompts.
- Scan for infostealers if passwords changed without explanation.
| Common attacks | Phishing, credential stuffing, spraying, brute force, keylogging, infostealer theft |
| Most common weakness | Reused passwords |
| Best defense | Password manager + MFA/passkeys + account alerts |
| If compromised | Change password, revoke sessions, check recovery methods, scan device |
Common password attack types
- Credential stuffing: using leaked passwords on other sites.
- Password spraying: trying common passwords against many accounts.
- Phishing: fake login page steals the password and sometimes 2FA.
- Keylogger/infostealer: malware captures typed or saved credentials.
- MFA fatigue: repeated prompts trick a user into approving access.
Run a full system scan after removal.
After uninstalling the suspicious app or deleting the threat, scan all drives to catch hidden folders, startup entries, and bundled files.

Is changing one reused password enough?
No. Change it everywhere it was reused.
Are passkeys safer?
Passkeys reduce phishing risk because they are tied to the real site/app.
What if my browser saved passwords were stolen?
Change important passwords from a clean device and scan the original PC for infostealers.
