Hello,
has several default account and passwords, which are used for login in
different scenarios. Please refer to the following figure.

PS:The telecomadmin
user, having the highest priority in the system, cannot use the default
password. Specifically, the telecomadmin user must change the password after
logging in to the system
l The system
displays a login failure message if the account and password for logging in to
the ONT by Telnet, SSH, or web page are incorrect.
l For account
management using the web page, the system will be locked if you input incorrect
user name and password three times within five minutes. One minute later, it
will be unlocked.
l For account
management using the CLI, the system will be locked if you input incorrect user
name and password five times within five minutes. Five minutes later, it will
be unlocked.
l Change the initial
password after logging in to the ONT. The initial account cannot be changed.
l Certain carriers
may customize accounts and passwords, which are different from the default
accounts and passwords listed in the preceding table. For details, contact the
corresponding carrier.
l Currently, the
root(cli) account password is the same as the account password of a common user
logging in to the ONT by web page. Before using the root(cli) account to manage
an ONT, perform security planning.
Thanks
