After downloading NEOLine, click [Import Wallet] and you will find that there are three methods: private key, encrypted key, and NEP2 file. Generally we choose the first one, the private key import.
The specific operation steps are as follows: Click [Import Wallet], select the private key, reset [Wallet Name] and [Wallet Password], and enter the complete private key backed up before.
But if you have forgotten your private key, you can also recover it with a JSON file, which is the third way to import the wallet through a NEP2 file.
The specific operation steps are: open the wallet, click [Import Wallet]-select the third item [NEP2 File]-click [Select file], you can log in to the wallet by importing your saved JSON file.
JSON File: JSON (JavaScript Object Notation) file is a file format containing lightweight data, which can be easily read by humans or machines.
The main function of the JSON file is that if your private key is forgotten, you can open the wallet by importing the JSON file and back up the private key again. However, when the JSON file is imported into the wallet, the password that needs to be entered is the password originally set by the wallet.
