Why can't TTLock app users log in via Open Platform API, and how to migrate them to my custom app with access to their existing locks?

[ashokadk457]

I’m building a custom app using the TTLock Open Platform API. I'm developing custom IoT-enabled smart lock solutions for our client and creating a custom app in which we plan to integrate multiple lock SDKs https://www.adequateinfosoft.com/custom-iot-enabled-smart-lock-solutions-for-businesses

Many of my users have already registered through the official TTLock mobile app and added their locks there.

However, when I try to authenticate these users via the /oauth2/token endpoint on https://api.ttlock.com/, it fails with "invalid account or password".

Only users who were registered via the Open API (/v3/user/register) are able to log in successfully and access lock data.

My problem:

• I can’t migrate existing TTLock app users into my app

• If I register them as new users in my platform, I can't access the locks they previously added

• TTLock locks are bound to their original TTLock user account and cannot be accessed via my Open Platform credentials

My questions:

• Why can’t official TTLock app users log in via the Open Platform?

• Is there a way to migrate existing TTLock app users and their locks into my Open Platform account?

• What is the best approach to move all existing users (with their locks) from the TTLock app to my custom app?
