Can administrators obtain the user's last login password modification time?

Hi there @hanguang5651552

You can find information about what admins are able to see in relation to their users here:

• Use the Activity Log in 1Password Business
• Create reports in 1Password Business

An admin can see when a user has changed their 1Password account password, which I hope answers your question, but if you're looking for something else in particular, let me know what you're aiming to do, and I'll be able to look into that. :)
