How to share a login that uses SMS for 2FA (lemmy.world)

We are a group of hobbyists managing a mailing list. Mailchimp insists on SMS authentication to login now which has scuppered our plans to spread the workload.

Are there any free / cheap services that would receive a text messages and forward it by email to several people? If not, is there an alternative way to deal with this situation? We’re not necessarily attached to mail chimp but delivery is important.

A TOTP app basically generates a token based on a secret key. If you share the secret key between the members of your group, any of them is able to generate the token. Maybe it is even possible to register several authenticators with different secret keys, then you would not need to share the key and, if a device gets lost, you could simply remove the compromised key from the list of valid keys.
