Keep your Google Authenticator codes synchronized across all your devices

Data encryption
Google encrypts data both in transit and at rest across our products. In certain products, we also provide the option of extra protection for your data with end-to-end encryption (E2EE). However, the use of E2EE can lock you out of your data permanently if you forget your password. To ensure a full set of options we will roll out optional E2EE in some of our products, like Google Authenticator, in the near future.
