How to reset AT password ?

Latest reply: Oct 30, 2018 03:20:54 380 9 9 1

The AT only supports a single user. That is, the console port user, Telnet user, and SSH user all refer to the same user. If the password is lost, you can enter UBoot to reset the user name and password of the device to the default value. The reset user name and password are admin and admin@huawei.com respectively.

 

Note:

If you need to restart the device to enter the uBoot view, the service will be interrupted. Please back up the device data according to the specific situation and try to select the time when the traffic is small.

Do not power off the device during this operation.

 

1. Connect and restart the device with the serial cable. When the message “Press f or F to stop Auto-Boot ......” appears, press “f” and type the password (default is “admin@huawei.com”). uBoot view.

If all passwords are forgotten, for devices with the Default button, you can press and hold the Default button for more than 3 seconds to restore the factory configuration. The user name and password of the device will be restored to the default values. For devices without the Default button, contact technical support personnel.

 

2. Run the defaultuser command in the uBoot view to reset the device username and password.

AAAA> defaultuser

Start setting whether to Change Password.....

Current Bootup Change PW is N

Do you Want To Change The Default password, Y or N : Y

AAAA>

 

3. Run the reset command in the uBoot view to restart the device.

AAAA> reset

Resetting...

 

4. After the system is started, modify the device username and password after logging in to the device using the default user. The username is huawei and the password is huawei@123.

<BBBB> system-view

[BBBB] local-user huawei password cipher

New Password(<8-16>/<56>):

Confirm Password:

[BBBB] quit

 

5. If the device is powered off abnormally, you can run the save command to save the configuration. You are advised to save the configuration file locally.

The reset boot password command resets the password of the BootROM/Bootload menu to Admin@huawei.com.
If you forget the password of the BootROM/Bootload menu, use the reset boot password command to set the password to Admin@huawei.com. Then you can use this password to enter the BootROM/Bootload menu.
