Sharing administration responsibilities

I work with an MSP and there are a few of us who are administering services for our clients. We're trying to figure out how to share 1Password. When you initially sign in you have to register your device. One of my colleagues says he last accessed this last year and now doesn't remember which computer it was from. When we try to sign in now we get:

1. Sign into 1Password on the Firefox session that you have used before.
2. Go to My Profile.
3. Under Pending Sign-ins, look for Microsoft Edge.
4. Select View.
5. Allow the transfer request.
6. Enter the verification code in the next step.

I'm waiting on the owner of the account to reset our account and get us back in. In the meantime, what's the best way to manage this? Our client has the Enterprise Edition enabling SSO support. For us as an MSP, how can a few of us administer this a few times a year, to on-board people or reset access for others? Do we each need our own account?
