Thoughts?
- m_eiman 17y agoThere are such systems available, e.g. http://www.google.se/search?q=authentication+sms+service http://www.google.se/search?q=authentication+sms+service In my opinion the best solution for two-factor logins is password plus SMS challenge. It requires a device, but at least it's a device you most likely already have. The solution might not be as useful in the US with the "pay for receiving messages" stuff, but if the service you're loggin into is important enough (bank etc) most people might not mind.
- JunkDNA 17y agoI have no experience with SMS other than as an average user. I'd love to know from someone more knowledgable than me, how secure this would be? From my basic understanding it seems that SMS would be hard to intercept on the phone network, but if a site is using an SMS gateway, it's not much safer than using email for two factor auth, right?
