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.
