Introduction

Password security raises many questions. This comprehensive FAQ answers the 50 most common questions about creating, managing, and protecting passwords. Whether you're a beginner or advanced user, you'll find clear, actionable answers here.

Password Basics

1. How long should my password be?

Minimum: 12 characters for standard accounts Recommended: 16 characters for most accounts Critical accounts: 20-32 characters (email, banking, password manager)

Why: Length adds exponential security. A 16-character password is exponentially stronger than an 8-character password.

Learn more: Password Length Guide

2. What makes a password strong?

Four factors:

1. Length: 16+ characters
2. Randomness: No patterns or dictionary words
3. Variety: Mix of character types
4. Uniqueness: Different for each account

Example strong password: xK9#mL2pQ7nR4vXt

3. Should I use special characters?

Yes, but length matters more. Special characters add complexity, but a long password without them is stronger than a short password with them.

Good: xK9#mL2pQ7nR4vXt8Yz3 (20 chars with symbols) Also good: CorrectHorseBatteryStapleMonkey (31 chars, no symbols)

4. How often should I change my password?

Modern recommendation: Only when compromised

Don't change:

• On a schedule (90 days is outdated)
• Just because

Do change:

• After a breach
• If shared accidentally
• If suspicious activity
• When leaving a job

Source: NIST guidelines (2017)

5. Can I reuse passwords?

Never reuse passwords. This is the #1 security mistake.

Why: One breach compromises all accounts using that password.

Solution: Use a password manager to generate and store unique passwords.

Password Creation

6. How do I create a strong password I can remember?

Method 1: Passphrase

• Use 4-5 random words
• Example: "Correct Horse Battery Staple"
• 25+ characters, memorable

Method 2: Sentence

• "I love coffee at 7am every morning!"
• 37 characters, easy to remember

Method 3: Don't memorize

• Use password manager
• Generate random passwords
• Only remember master password

7. Should I use a password generator?

Yes, absolutely. Password generators create cryptographically secure random passwords that are impossible to guess.

Benefits:

• Maximum security
• No human bias
• Truly random
• Customizable length

8. What's wrong with using patterns?

Patterns are predictable:

• "Password1" → "Password2" (common)
• "Summer2024" → "Fall2024" (predictable)
• "qwerty123" (keyboard pattern)

Computers crack patterns easily. Use truly random passwords instead.

9. Can I use my name or birthdate?

Never use personal information:

• Names (yours, family, pets)
• Birthdates
• Addresses
• Phone numbers
• Social Security numbers

Why: Easily guessed or found on social media.

10. What about password hints?

Don't use password hints. They weaken security by providing clues to attackers.

Better: Use password manager with secure recovery options.

Password Managers

11. What is a password manager?

A secure digital vault that stores all your passwords encrypted. You remember one master password; it remembers everything else.

Features:

• Generate strong passwords
• Auto-fill on websites
• Sync across devices
• Breach monitoring
• Secure sharing

Learn more: Password Manager Guide

12. Are password managers safe?

Yes, very safe. They use military-grade encryption (AES-256) and zero-knowledge architecture.

Even if compromised: Your passwords remain encrypted and inaccessible without your master password.

Much safer than: Reusing passwords, weak passwords, or writing them down insecurely.

13. Which password manager should I use?

Top recommendations:

• Bitwarden: Open-source, free, excellent security
• 1Password: Premium features, user-friendly
• Dashlane: Advanced features, VPN included

All are secure. Choose based on features and budget.

14. What if I forget my master password?

Most password managers cannot recover it (zero-knowledge design).

Prevention:

• Use memorable passphrase
• Write down securely (home safe)
• Set up emergency access
• Save recovery codes

This is intentional - ensures your passwords stay secure.

15. Can I share passwords safely?

Yes, through password manager sharing features:

• Encrypted sharing
• Revocable access
• Audit trail
• No plain text

Never share via:

• Email
• Text message
• Phone call
• Written note

Two-Factor Authentication

16. What is two-factor authentication (2FA)?

Second verification step after your password:

1. Something you know (password)
2. Something you have (phone, security key)

Result: Even if password is stolen, attacker can't access account.

Learn more: Multi-Factor Authentication Guide

17. Should I enable 2FA everywhere?

Yes, on every account that supports it:

• Email (most important)
• Banking
• Social media
• Shopping
• Work accounts

Impact: Blocks 99.9% of automated attacks.

18. What's the best 2FA method?

Ranking:

1. Hardware security key (YubiKey) - Best
2. Authenticator app - Good
3. SMS - Better than nothing

Avoid SMS for critical accounts due to SIM swapping risks.

19. What if I lose my 2FA device?

Backup methods:

• Backup codes (print and store securely)
• Multiple 2FA methods registered
• Backup hardware key
• Recovery email/phone

Always set up backups before you need them.

20. Can 2FA be hacked?

Some methods can:

• SMS (SIM swapping)
• Push notifications (push fatigue)

Hardware keys cannot - phishing-impossible by design.

Best practice: Use hardware keys for critical accounts.

Security Practices

21. Is it safe to write down passwords?

It depends:

• Safe: Written and stored in home safe/locked drawer
• Unsafe: Sticky notes, wallet, desk

Better: Use password manager instead.

For elderly: Written passwords at home often safer than weak/reused passwords.

22. Should I use the same password for similar sites?

No. Each account needs a unique password.

Why: Breach of one site compromises all accounts with that password.

Example: Don't use same password for Gmail and Outlook, even though both are email.

23. How do I know if my password was breached?

Check: Have I Been Pwned

Signs:

• Unexpected password reset emails
• Suspicious account activity
• Can't log in
• Emails you didn't send

If breached: Change password immediately.

• System hashes it
• Compares hash to stored hash
• Cannot reverse hash to get password

Good algorithms: bcrypt, Argon2, PBKDF2

Learn more: Password Hashing Explained

32. What is encryption?

Two-way process that scrambles data:

• Encryption: Plain text → Encrypted text
• Decryption: Encrypted text → Plain text

Used for: Storing passwords in password managers, transmitting data securely.

33. What is end-to-end encryption?

Data encrypted on your device, transmitted encrypted, only decrypted on recipient's device.

Server cannot read it - true privacy.

Examples: Signal, WhatsApp, ProtonMail

34. What is zero-knowledge architecture?

Service provider cannot access your data even if they wanted to.

How: Encryption happens on your device with key they don't have.

Used by: Good password managers, encrypted email services.

35. What is a brute force attack?

Trying every possible password combination until finding the right one.

Speed: Billions of attempts per second with modern hardware.

Protection: Long passwords (16+ characters) make brute force impractical.

Use for: Device unlock, convenience layer Don't use as: Only authentication method

Combine: Biometric + strong password + 2FA

38. What is credential stuffing?

Attack using leaked passwords from one site on other sites.

How it works:

1. Attacker gets leaked passwords
2. Tries them on other sites
3. Succeeds if you reused password

Protection: Unique passwords per site.

39. What is a dictionary attack?

Trying common words and phrases as passwords.

Why effective: Many people use dictionary words.

Protection: Random passwords, not words.

40. What is phishing?

Fake websites/emails trying to steal your password.

Common tactics:

• Fake login pages
• Urgent emails
• Too-good-to-be-true offers
