How to give a manager access to the marketplace without transferring a password?

Question

Information Security

Essence of the question:
There is a marketplace in which there is no possibility to create a separate account for a manager.
I plan to rent a remote desktop.
Is it possible to make sure that an employee can log into the account at any time without knowing the password itself?
Perhaps there are some extensions?

I would be grateful for any advice.

I need this in order to hide the sections I need from him (I think just do it through the hosts)

Answer 1

The answer is LastPass

Answer 2

Waf if you need to hide sections, just block everything in traffic that is related to closed sections. AIM, PIM for access, there you can make it so that after each exit the password changes and every time you enter an SMS with OTP flies
