Need help... is there a way to reset the switch login password?

This needs to be discussed in different situations, you can check whether these situations can solve your current problem.
Scenario 1: All Default Passwords Are Changed and All Passwords Are Forgotten If you change all default passwords and forget the console port login password, all STelnet/Telnet login accounts and passwords, and BootROM/BootLoad passwords:
·For a switch that has the PNP button, you can press and hold the PNP button for more than 6 seconds to restore the switch to factory settings and restart the switch. The following figure shows the PNP button.
·If the switch does not have the PNP button, return it to the factory for repair.
Scenario 2: Default Passwords Are Forgotten For S series switches running V200R020 and later versions, no passwords are configured for default accounts, and users must configure new passwords for logging in to the switches. In this situation, scenario 2 is not involved.
However, for S series switches running versions earlier than V200R020, there is no default STelnet/Telnet login password, but there are default console port login password, default BootROM/BootLoad password, and default web login password. These default passwords may vary according to the switch version.
If you always use the default passwords and have not changed the passwords, you can obtain the default accounts and passwords according to S Series Switches Default Usernames and Passwords (for enterprise users or carrier users). The permission level of this document is C (customer support level). If you need to upgrade the permission level, see the help document on the website.
Scenario 3: The Console Port Login Password Is Forgotten Three methods are available to recover the console port login password.
·Method 1: Log in to the device using STelnet or Telnet and change the console port login password.
·Method 2: Clear the console port login password in the BootROM/BootLoad menu and change the console port login password.
Scenario 4: The STelnet/Telnet Login Password Is Forgotten ·If you forget the login password of an STelnet/Telnet account, you can use another STelnet/Telnet account with administrator rights to log in to the device and reset the password. For details, see Method 1.
·If you forget the passwords of all STelnet/Telnet accounts but can log in to the device through the console port, see Method 2.

Method 1: Use an STelnet/Telnet Account with Administrator Rights to Log In to the Device and Reset the Password

1.Log in to the switch using the STelnet/Telnet account with administrator rights.
2.Change the STelnet/Telnet login password. The following example describes how to change the STelnet/Telnet login password of VTY0 to VTY4.

Method 2: Log In to the Device Through the Console Port and Set a New STelnet/Telnet Login Password

If you forget the STelnet/Telnet login password but remember the console port login password, log in to the switch through the console port and set a new STelnet/Telnet login password.
Scenario 5: The BootROM/BootLoad Password Is Forgotten but the Console Port/STelnet/Telnet Login Is Available If you can log in to the switch through the console port, STelnet, or Telnet, log in to the switch and restore the default BootROM/BootLoad password. You can obtain the default accounts and passwords according to S Series Switches Default Usernames and Passwords (for enterprise users or carrier users). The permission level of this document is C (customer support level). If you need to upgrade the permission level, see the help document on the website.
Scenario 6: The Web Login Password Is Forgotten but the Console Port/STelnet/Telnet Login Is Available If you can log in to the switch through the console port, STelnet, or Telnet, log in to the switch and reset the web login password. In the following example, the web login user name is admin123 and the password is test@123.

LOST ROUTER LOGIN PASSWORD
If you have forgotten your personal router login password there is no way to recover it. You will have to reset the router. This means all the settings on the router will be reset to factory defaults. It also means that all your connected devices will need to be connected again with the new security information (WEP, WAP, etc,) . You will need the default admin login name and the default admin password. This can be found in the user guide that came with the router. This can usual be found online at the router manufacturers site.
There is usually a button or a switch hidden in a pinhole opening on the back of the router. Pressing and holding the switch for 10 seconds or so will cause the reset and usually the LEDs will flash and blink for several seconds as the router firmware sestets and clears out the old information.
If you are trying to get into someone else's router illegally there is no way to find out their login password.
For future reference, write the password down, or a hint at what the password is, on a piece of tape and secure it on the bottom of the router. I use my cell phone memo function to store all my passwords.

Default password for most of the modem is "admin"
If it doesn't help, then it will be mentioned in your modem user manual. For resetting your modem, you can use the hardware reset switch also. You can reset using that by inserting a small pin/needle into the hole located somewhere behind the modem.

If you are unable to perform an Administrator login (because the Username and
Password information has become corrupted, or you have forgotten it, for
example), there is a procedure you can use to clear the login information.
To clear the login information do the following:
1. Power off the CN8000 and remove its housing.
2. Use a jumper cap to short the jumper on the mainboard labeled J6.
3. Power on the switch.
4. When the front panel LEDs flash, power off the switch.
5. Remove the jumper cap from J6.
6. Close the housing and power on the CN8000.
After you start back up, you can use the default Username and Password (Login: administrator, pass: password).
