Password Managers Overview
Essential guide to password managers: why you need one, how they work, and comparing top options.
Why You Need a Password Manager
Average person has 100+ online accounts. Reusing passwords is dangerous - one breach exposes all accounts. Password managers generate, store, and autofill unique strong passwords for every account.
Benefits of Password Managers
Unique Passwords
Different password for every account. One breach doesn't compromise everything.
Strong Passwords
Generate 20+ character random passwords. Impossible for humans to remember or crack.
Convenience
Remember one master password. Manager autofills login forms. Sync across all devices.
Phishing Protection
Won't autofill on fake sites. URL matching prevents credential theft on lookalike domains.
Security Audit
Identifies weak, reused, or compromised passwords. Monitors for data breaches.
Secure Sharing
Share passwords securely with family or team without revealing actual password.

How Password Managers Work
Master Password

Security Considerations
Master Password Strength
Use 4-5 word passphrase. Diceware method ideal. Never reuse from other accounts. This is your single point of failure.
Enable 2FA on Manager
Authenticator app (not SMS) for master password. Hardware key (YubiKey) for maximum security.
Avoid Browser Built-In Managers
Chrome/Safari managers less secure. No encryption at rest. Accessible to malware. Use dedicated manager.
Regular Backups
Export encrypted backup quarterly. Store offline. Protects against account loss.
Free vs Paid
Free Tier Limits
Often single device type or device limit. Limited sharing. Basic support. Still better than reusing passwords.
Premium Benefits
Unlimited devices. Priority support. Advanced 2FA. 1GB+ encrypted storage. Family sharing. Breach monitoring.
Recommendation
Bitwarden free tier excellent for individuals. 1Password/Dashlane for families. Premium worth it for convenience.
Migration & Setup
Choose Provider
Research security track record. Check reviews. Most offer free trials. Start with Bitwarden if unsure.
Create Strong Master Password
Use Diceware or 4-word passphrase. Write on paper, store securely offline. Never forget this!
Import Existing Passwords
Export from browser. Import to manager. Most support CSV format. Review for duplicates/old accounts.
Install on All Devices
Desktop app, mobile apps, browser extensions. Test autofill functionality. Enable biometric unlock.
Change Critical Passwords
Generate new unique passwords for email, banking, important accounts. Use manager's audit tool.
Enable 2FA
Add authenticator app 2FA to master password. Test recovery codes. Store codes securely.
Best Practices
- Use maximum length passwords (20+ characters) for all accounts
- Include uppercase, lowercase, numbers, symbols unless site restricts
- Never use personal information in passwords
- Change passwords immediately after breach notifications
- Use different passwords for work vs personal accounts
- Store recovery codes in manager's secure notes
- Review and delete old/unused accounts quarterly
- Share family account, not master password
Common Concerns
"All Eggs in One Basket?"
Yes, but encrypted basket. Far safer than reused passwords. Enable 2FA. Choose reputable provider.
"What if I Forget Master Password?"
Unrecoverable by design (zero-knowledge). Write it down. Set up emergency access. Some offer account recovery with delays.
"Can't Remember Master Password"
Use passphrase (4+ random words). Muscle memory develops quickly. Practice typing it daily for a week.
