PuTTY connection

Thanks to those who took the time to reply.  The 'big' hint was that password entry is not reflected in the emulation screen as I expected. 

The last time I used PuTTy was in 2015 with a program called Midnight Commander.

At that time, with the PuTTy emulator I had available, I was able to load the emulator and log on to "admin" with the system password.

Our use of PuTTy is low -- not used since 2015 and I want to verify what my research shows...

PuTTy will no longer open with a Windows shortcut that contains the password as part of the command line.  Is that true?

"admin" account reference has been replaced with "root".  That change has occurred in the past three years?

The password we use for every system is different and is about 16+ characters -- typical upper/lower/special.  In the Windows environment we use cut/paste to enter the password if needed.  For all practical purposes it is not possible to type the password correctly since the actual input is not reflected and keyboard input is subject to the fat finger syndrome. 

Security is important but in this manner it is not paramount since the physical security essentially isolates selected Windows systems.  Any recommendations for a way to establish a PuTTy connection, including the password, would be appreciated.
