####root password forgot######
We often encounter this situation
Frequent password changes are for security, but memory is a big hassle
No one should put too much trust in their own memory
How should this be the case? (it's so tricky.)
Enter the topic below
1. Reboot the system
2. In the system startup phase, press the up and down keys to stop the system system boot
