🔐 Top 10 Password Security Tips Every Developer Should Know

Passwords are the first line of defense in your digital security. Weak or reused credentials are still one of the most common causes of breaches. Whether you're building apps or managing infrastructure, here are 10 expert-recommended practices to secure your accounts and systems.

1. Use Long Passwords

A minimum of 12–16 characters is recommended for all important accounts.

2. Combine Character Types

Include uppercase, lowercase, numbers, and symbols for stronger entropy.

3. Avoid Common Words and Phrases

Simple or dictionary-based passwords are vulnerable to brute-force and dictionary attacks.

4. Never Reuse Passwords

One password for multiple services = one breach away from disaster.

5. Store Passwords Securely

Use trusted password managers like Bitwarden, 1Password, or KeePass to safely store credentials.

6. Enable Multi-Factor Authentication (MFA)

Add an extra layer of protection by enabling MFA wherever possible.

7. Rotate Passwords Periodically

Set a recurring schedule (e.g., every 3–6 months) for high-risk systems.

8. Don’t Store Passwords in Code

Never hard-code passwords in repositories, scripts, or configuration files. Use secrets managers instead.

9. Monitor for Breaches

Use tools like haveibeenpwned.com to check if your email/password has been compromised.

10. Educate Your Team

Make password hygiene part of your onboarding and security training process.
