If you are looking for a way to change the WiFi password for Viettel using a phone, you first need to connect your phone to that WiFi modem and know the Username and Password to log in to the WiFi modem. Here are the detailed steps.

Benefits of changing Wi-Fi password

Changing the WiFi password will help you remember the WiFi password easier. For stores, restaurants, and cafes, changing the WiFi password is extremely important to help customers easily access and use the WiFi of the establishment.

In addition, if you suspect that someone is using your WiFi without permission, you should also change the password to ensure security. During use, you should also change the WiFi password regularly to enhance security.

How to set a secure WiFi password

A study shows that passwords with 4-11 characters consisting of only numbers can be cracked immediately. Passwords consisting of only 8-9 lowercase letters are not secure either. A password is considered secure when it contains a 10-character sequence including uppercase letters, lowercase letters, numbers, and special characters.

Furthermore, you should not set the WiFi password the same as personal information such as phone numbers, names, and home addresses. And most importantly, you need to set a password that is easy to remember for yourself and family members but difficult for others to guess.

Once you have come up with a secure and memorable WiFi password, let’s find out how to change the Viettel WiFi password using your phone.

How to view the Username and Password of the WiFi modem

Before changing the WiFi password, you need to know the login username and password to log into the WiFi modem (different from the WiFi name and password).

By default, with all network modems including Viettel WiFi modem, the login username and password will be displayed on the back of the modem, the login username is always admin, and the password will be the name of the modem manufacturer plus a random sequence of characters.

In case the Username and Password have been changed, you can use a small object like a toothpick or a SIM card ejector tool to reset the modem to the default Username and Password information mentioned on the modem.

After you have found the Username and Password of the WiFi modem, let’s move on to the next steps.
