After various hacking/phishing attempts on MyEtherWallet, it became standard to not use private keys on MEW or double-check URL before accessing account. Many people already lost faith in MEW and it really became difficult to access Ethereum address.
Then came MetaMask and solved whole problem. It works as browser-extension thus solved the problem of phishing attack all together. Secondly, seed-generation and input take place at client-side (not server-side). Thus user's seed is not saved anywhere except user's own browser.
Using MetaMask is simple as 1-2-3. User first have to generate seed which he can write and save somewhere safe. Next he has to choose password for the account and that's it. With seed, user can access his wallet on any device.
Metamask is one-stop portal to all Ethereum networks. Deploying Smart Contracts made easy with MetaMask. MetaMask payment window automatically pops-up when paying for deploying smart contract on tools like Remix.
In short, MetaMask is best wallet-provider to access Ethereum addresses.Siehe vollständige Bewertung
