Dear Praveen Kumar D (INFOSYS LIMITED),
Thank you for visiting the Microsoft Community.
I understand that you seem to be hoping that you can get your work account back by creating a key, and I understand how you feel.
It may be true that Android 14 does not support the creation of pass keys, this may be because it has an API or feature that does not support creation and management. It is suggested that you can use other recognised access such as password or biometrics or create it using other 3-way software.
I wish I could solve your problem, but your issue seems to require a working account or more specialised support in the Android 14 mobile feature set, and it is recommended that you can get help with this on the Enterprise section of the community or in the Android System Support Centre.
We sincerely hope that if you contact the right department, your issue will be handled properly. Thank you for your understanding!
Best regards
Isabella-MSFT | Microsoft Community Support Specialist
