@Solla-topee I agree. Would be really important to offer the feature to update the email address for the account and also to allow for updating wifi and passwords. For selling smart home, changing email addresses, security and much more. It's hard to start over re programming everything especially if you have lots of plus and switches and automation and scenes. It's quite overwhelming. Definitely love my smart home, but without this option, I would seriously consider a different brand for the next time. Makes it hard to update internet to faster speeds or get Wi-Fi extenders or change providers. Always lots of valid reasons people might need to update wifi and/or primary email address.

This has been a "feature" request for over three years with no action being taken. But it's not really a feature - it's fundamental functionality. How can you build a system that does not let a user change the email address associated with their account? Is there a responsible product manager, or do your engineers just function by seat of the pants? It's absurd to expect your users to delete and reprogram dozens of devices any time that their email address changes for whatever reason.

I spent over four decades as a software engineer, product manager, and product marketing VP, so I'm qualified to say the response from TP-Link is unprofessional and unacceptable.

Add me to the list for wanting an easy way to change email addresses.  I have several KASA devices and the thought of having to reset them all, or start all over is NOT acceptable,   Even APPLE allows you to change your email address, with all of its associated complications.  

TP-LINK - ADD THE "CHANGE YOUR EMAIL ADDRESS" FEATURE PLEASE.
