Websites for Generation of Paper Wallets
MyMonero.com is a web wallet developed and maintained by one of the Monero core developers, Riccardo Spagni. Although the website in itself might be secure, the usage of web wallets is much less safe compared with the alternatives. Phishing, key loggers, and someone finding your seed are some of the risks.
