I am relatively new to the eth community and i am currently trying to find a good way of using eth blockchain to create a signuo/signin mechanism. it turns out to do so in browsers, something like Metamask is needed.
What is Metamask ? what does it do ?
What i need to know is what exactly should i do when having to use the users eth address to authenticate him/her ? in my recent attempts i had to use a login box like this one :
Of course i do have code behind that verifies the address and the login infos, but with metamsk i still don't grasp what should i do.
