We are a very small Class 1 library. Several vendors using two-part authentication require listing a mobile phone number with them, so I've had to use my personal phone number for a few.

GoDaddy will only let me change a mobile number, not delete it, even though my two methods of confirmation are now email and the Google authenticator app.

Do you have a library mobile phone plan? If so, do you recommend it, especially for one line? 

And/or, do your trustees have mobile phones supplied by the library?

Thanks in advance,
