Is it possible to have 2 Mobile Authenticators for 2 different accounts in the same phone? I am poor, I can't afford to buy a new phone for my 2nd (support) account.

1 phone, 1 app with 2 accounts.

Can I share my phone number between multiple accounts?

Yes. You may use the same phone number on multiple accounts. You may enable Steam Guard Mobile Authenticator on multiple accounts on the same phone by logging in to each account within the app and following the procedure to enable the authenticator on each account. The app will provide codes for all accounts regardless of which account is currently logged in to the app. Accounts with the same phone number may be treated as the same identity with respect to the Steam Subscriber Agreement, policies, or restrictions.
