Sometimes usernames and passwords are very hard to remember these days, with different online companies having different requirements for a good password - long, short, numbers, case sensitive etc. Then you would have to remember all these different passwords for doing different online things - email, bank, social media, Newspaper sites etc. Well Google hopes to remove these terrible thoughts by experimenting with different hardware that will act as your "online password", with examples being a smart ring for your finger, a cryptographic USB stick, or a token embedded in smartphones.
