4. How to create a strong Wi-Fi password
A weak Wi-Fi password is like an open door for neighbors or hackers. To protect your network, follow these rules:

- 🎲 Complexity: combine upper/lower case letters, numbers and symbols (
!,@,#). Avoid words from the dictionary. - 🚫 Taboo: Do not use personal information (dates of birth, names, phone numbers).
- 🔄 Update: Change your password every 3-6 months, especially if guests connect to the network.
Examples of strong passwords:
| Password type | Example | Security level |
|---|---|---|
| Simple (not recommended) | qwerty123 |
❌ Low |
| Average | Summer2026! |
⚠️ Average |
| Difficult | P@ssw0rd_L0ck$ |
✅ High |
| Maximum protection | 7x!Kp9@Lm#2vQ1 |
⭐⭐⭐ Excellent |
