Changing Huawei ONT HS8545M5 password with MD5 and SHA256 hashes

Its always good to change the default password of your Network Devices.
Below is the instruction on how to change the default password for your Huawei ONT.
It works for Huawei ONT model H545M5 but I am sure it works the same of other Huawei ONTs as well.

1. First of all, from your browser, you need to go to router’s IP. The default should be 192.168.100.1
   If that doesnt work, do the IP scan first.
2. Then you need to know the default username and password. Default for HS8545M5 is
   Account : telecomadmin
   Password : admintelecom
   
3. Once logged in, navigate to System Tools > Configuration File
   Download the configuration file
   You will download hw_ctree.xml file
   ** Before making any changes, its a good idea to save the back up of your configuration file. ***
   
   
4. Open with any text editor and search for Username and Password fields.
   Copy the password hash just in case something goes wrong.
   
   
5. Huawei devices uses two step hashes. MD5 and SHA256.
   If you are a Linux user, use below commands to create hashes 5 new password.
   OR
   You can also use online has converters from below link.

   A. First convert your plain text password to MD5 and then convert your MD5 to SHA256 hash.
   
   

──╼ $echo -n newpasswd | md5sum

e08df5d370e3a10fb6a005763877b60d –

$# Now Convert e08df5d370e3a10fb6a005763877b60d to SHA256

└──╼ $echo -n e08df5d370e3a10fb6a005763877b60d | sha256sum

With your new SHA256 hash, update your config text file and upload config text file to your ONT.
Reboot the ONT and login with the new password.

Mind you again , its always a good idea to keep the backup of your config file in case something goes wrong.
