Weak passwords are the main reason home networks are hacked, according to statistics. Kaspersky By 2026, 68% of routers in Russia will use passwords like 12345678 or qwerty, which are hacked in seconds. To protect your network, follow these rules:

What should be in the password:

• 🔤 Combination of uppercase and lowercase letters (AaBbCc).
• 🔢 Numbers (0-9) and special characters (!@#$%, if supported).
• 🎲 Lack of personal information (date of birth, names, addresses).

Examples of strong passwords:

• Green$Tree77!Moon
• Purple@Rain2026#Sky
• BlueOcean$99*Fish

What to avoid:

• ❌ Key sequences (qwerty, 12345678).
• ❌ Repeating characters (aaaa1111).
• ❌ Words from the dictionary (password, iloveyou).

Promsvyaz routers with firmware 2023+ support a password generator in the web interface (section Wi-Fi → Generate a password). This function creates a random combination of 16 characters, taking into account security requirements.
