What are the solutions for implementing Single Signe-On (pass-through / single authentication)?

Question

User identification

Ideally, I would like to be able to work on the following scenario. A USB key is being prepared, which stores all the necessary accounts and passwords for applications and websites on the Internet. The end user does not need to know the credentials, he must insert the USB key into any computer and access the resources.

Answer 1

Didn't come across such SSO solution.
If all applications support certificate authentication, then the most convenient way is to use a token or a smart card.
The SSOs I have worked with collect passwords from various applications and store them in Active Directory. Thus, the user can use the SSO functionality from any PC on the network by logging into his account.
