Metamask login is a browser plugin, available as the Metamask login Chrome extension or Firefox Add-on. At its core, it serves as an Ethereum wallet: By installing it, you will get access to a unique Ethereum public address, with which you can start sending and receiving ether or tokens.
For logging in to MetaMask, you are required to either use the biometric authentication process or use your MetaMask login credentials. However, one who usually logs in with a biometric authentication process may easily forget his login password. To reset this password, you simply need to click on the "reset wallet" option on the main login screen.
MetaMask Wallet service offers you to store, buy, sell and even swap crypto tokens. In addition to that, you’d also be able to pay your bills via crypto wallets, which have been launched in several variants too. The wallet services are used for storing and protecting crypto money but you can also trade using them.
