HSA contributions on family HDHP not to primary plan beneficiary

Through 2019, I used to have family coverage HDHP through my employer and made the annual max contributions to the HSA each year. 

 

For 2020, we switched to an HDHP for the family through my wife's employer.

 

For 2020 HSA contributions -  can I contribute the family max contribution amount for 2020 into my HSA account? Or do I have to establish a separate HSA account in my wife's name (the HDHP primary person being my wife for 2020) ? 

 

Prefer to keep it simple and not create one more account that I will have to manage, if permitted.

Thank you
