How can someone become a moderator?

Maybe this is a silly one, but I've been searching and nothing comes up.

I've been exploring Instagram and I don't see an option to make someone else admin/editor/moderator of an account (Facebook allows to do this on pages).

If I need help to manage a page, how can I make other people moderators? Do I need to give them the login details? If so, is this secure?

Thanks in advance

there is no option for this. you can still open you IG account on many devices

Only way is to give them your login details. Anyway, you should never give them password of email that is used for account creation. In case someone decides to steal your account, the email is your only way to get it back.

usually you would use an app or something for IG that would give them permission to post. Then if you part ways you remove the auth from that app they had access to

Or, do the Kmart blue-light special, and just enter the account info on their phone app or browser. They won't know what the password is.

Problem with the blue-light special is if they change the email address, they can reset the password.

But, maybe they ain't that smart. Other than that, your good man.
