Hi @MissA21
Currently, Teams does not introduce a method to directly enter Teams by scanning the QR code. To get this feature more quickly, you can send a feedback directly to Microsoft Feedback to add it in future updates.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
However, after you successfully log in once and your Teams cache has not been cleared, your account will be saved in Teams so that you can log in easily next time without having to re-enter your email account.
