I’m about to bring on a couple of users for a base that I’ve developed for them. But I’m a little confused about how to manage this.

1. 
   I want these new users — let’s call them Ann and Ben — to have their own individual accounts. I want them to have to log in with separate passwords, so I can get the right values into the “Created By” and “Modified By” fields, and so that they can see each other as users when they’re writing targets ("@BenBenson", etc).


2. If possible I would like to create the accounts for them, so that I can assign them passwords. (This is something I can do as a FileMaker developer. Is this even possible with Airtable? Is there any way to be sure that users have reasonably strong passwords protecting their accounts?)


3. And I want to be responsible for paying for their accounts.
   

#1 and #3 are the more important things here.

I know how to share the base with them. I just don’t quite understand what happens after I send them an invite. Will they be asked for credit card? I don’t want that.

.

Another question. If their account is created on my credit card (if that’s possible), and I share the base I’ve created with them as editors, what sort of privileges will they have within their own new accounts? Will they be able to create a new base on their own? Will it be added to my workspace? Will they be able to share their new base with somebody else who will suddenly be a monthly charge on my credit card that I did not expect?

.

Final question: If in future I decide to set them free and ask them to shoulder the cost of their own accounts, how do I go about doing that? They will probably at that point both want to be paid for by a single account, say, Ann’s account. (She’s the office manager, pays the bills etc.)

Thanks in advance.
