Do I need to change my Wi-Fi password?
Wireless routers allow their owners (called administrators) to manage the Wi-Fi network through special login details.
Anyone who knows the username and password can log into the router, which immediately grants complete access to the device’s features, as well as information about any devices connected.
Manufacturers often set up new routers with the same default username and password. In many cases the username is often simply the word “admin” or “administrator”. The password is typically blank, or is something very guessable like “admin”, “public”, or “password”.
When you buy a new router, you should change the username and password immediately. This will prevent any hacker using common terms to get in.
To combat hackers, manufacturers now often provide random, individual passwords with routers. These are often written on stickers on the router itself. These are more secure, but are often hard to remember. You should consider changing the password to something that is memorable, unique, and difficult to guess.
There are other ways to break into Wi-Fi networks, so it is also recommended that you change your Wi-Fi password every 30-90 days. This will boot out anyone that has gained illegitimate access, and ensure your network is only used by those you want.
Just as a final tip, you should also ensure your Wi-Fi encryption is WPA2-PSK or WPA2-AES. These are the most secure protocols generally available, and very difficult for hackers to crack.
