about authentication and user achievements

i wanted to ask what would be the best authentication method to use in photon ? because i need to store player all time records such as how many kills the player has done , how many time has the player died and how many games has the player played ? as a scoreboard or achievment list as other multiplayer game has it ? and is it evn possible in photon like how we have it in pubg when a user sign in his achievments and level are shown to him and other player?
