Problems with connection for 2 identicle Huawei 8 phones -spotify

[nsjc75]

I have bought 2 identicle Huawei Honor 8, phones, for me and my wife. 

Im having problens connecting to Spotify Premium.

The phones have the same model.nr. FRD-L09

If i play music on my phone, it will change 'phone' to hers and play there insted, as we have the same model.nr. 

How can i trick Spotify into thinking that we have different phones?

We have different email adresses.

thanks

neil
