1 Apple ID and two phone #s for iMessage

[ReformedTexan]

we use my apple ID.
we both have iPhones
I want iMac desktop to have her phone number in the iMessage (because it is her computer)

Right now iMessage on her computer has my phone number associated with it. How can I change it to her phone number?

She would need her own Apple ID.

You need her AppleId on the iMac for this to work.
