Is there any way to check the initial password of Firewall(vSRX) later?
There is no way to check the initial password later. If you do not know the password of the initial user, please execute "reset password" from the customer portal.
After logging in for the first time, we recommend that you change the password by the following procedure so that the customer can manage the password.
Password change procedure
1. Login as root.
2. Execute the cli command. (The prompt changes from "%" to ">".)
Execute Configure command. (The prompt changes from ">" to "#".)
3. set system root-authentication plain-text-password
Enter password twice
4. Execute the commit command to reflect the change.
5. Execute exit command to exit Configure mode
