MetaMask^

MetaMask is a self-custodial wallet that lets you access blockchain applications and web3. To log in, download MetaMask or use the browser extension.

MetaMask also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™), so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it.
