Exclusively for Mi/Redmi phones there is dual apps option by default. you can make two copies of any app. But for the rest of the phones you can only have dual chat apps like whatsapp etc not other apps. If you have secure folder option in your samsung phone then you can move an app to secure folder and you will have two copies of the same app. one in secure folder and one outside. And you can login independently on both. if you don't have secure folder option then you need to install 3rd party app from playstore like (multi parallel) or (parallel apps) to do the same thing.
