20 Password Security Tips You Can Use Today
Password advice often gets repeated in vague terms — "be careful," "use strong passwords." Here are twenty specific, actionable tips, organized so the highest-impact ones come first.
The five highest-impact changes
- Stop reusing passwords across accounts — this single habit prevents more account takeovers than any other change.
- Enable two-factor authentication on email first, then banking, then everything else.
- Get a password manager and let it generate and store passwords for you.
- Use a strong, unique passphrase for the password manager's own master password.
- Check your existing passwords against known breach data using a breach checker.
Ten more habits worth building
- Use at least 12–16 characters for any password you generate.
- Never reuse a security question's real answer — use a random string instead.
- Don't trust a password just because it satisfies a site's composition rules.
- Review connected third-party apps on your important accounts periodically.
- Be suspicious of any message urging urgent login action.
- Verify a link's actual destination before clicking, especially in unsolicited messages.
- Use app-based or hardware-key 2FA over SMS where a service offers the choice.
- Keep your devices' software updated to patch known vulnerabilities.
- Don't write passwords on paper as your primary storage method.
- Avoid personal information — names, birthdays — in any password or PIN.
Five habits for ongoing maintenance
- Don't rotate passwords on a fixed schedule without reason — change them based on evidence of exposure instead.
- Periodically audit which accounts still have access to your email or social media.
- Have an offboarding plan for shared credentials if you run a small team.
- Keep a secure backup of your password manager's master passphrase, separate from your devices.
- Revisit your setup roughly once a year, since guidance and available tools continue to improve.
Why these are ordered by impact, not alphabetically
Not every tip on a list like this carries equal weight, and treating them as equally important can lead to spending effort on marginal improvements while skipping the changes that matter most. Password reuse elimination and MFA adoption alone address the overwhelming majority of realistic account-takeover risk — the remaining tips are genuine improvements, but they're refinements on top of that foundation, not substitutes for it.
Frequently asked questions
Do I need to implement all twenty tips right away?
No — start with the first five, which address the large majority of realistic risk. The rest are worth building over time rather than all at once.
Which single tip matters most if I can only do one thing today?
Enable two-factor authentication on your email account. It protects the account that can reset almost everything else you own.
Is this list different for businesses versus individuals?
The core principles apply to both, though businesses benefit from a written policy and centralized password manager administration on top of these individual habits — see our small business guide for that angle specifically.
How do I know if I'm actually following these tips correctly?
Use the tools referenced throughout this site — a strength checker, breach checker, and generator — to verify your current setup rather than assuming it's adequate.
Will following all of these guarantee I'm never compromised?
No security practice offers an absolute guarantee, but following these substantially reduces your realistic risk against the attack methods that account for the overwhelming majority of real-world compromises.
Are these tips ranked the same for businesses as for individuals?
The relative priority is similar, though a business context adds organizational-level considerations like policy documentation and offboarding that don't apply to individual use.
How often should I revisit this list?
An annual review is reasonable, since new tools and updated guidance periodically shift what's considered highest-impact, even though the core fundamentals tend to remain stable.
Conclusion
Twenty tips is a lot to take in at once, but the underlying priority is simple: eliminate password reuse, add MFA, and use a manager. Everything else on this list strengthens that foundation rather than replacing it.
