I'm developing some mobile app using react-native, and server for it.
I need to make a secure login to a server from an app. For the server, I'm using Spring Boot and Spring Security.
I know that for site's Spring use form Login, and there are nothing difficult in configuring it, but when it comes to login from mobile app, i can't get any information about it.
If you know ways to do this, I will be very grateful for any info on this issue.
The way you mention about is stateful authentication.
You have to take a look token based / stateless authentication.
There are many tutorials about implementing JWT Authentication on Spring. You can google about it.
