We are pleased to see a continued (albeit slow) growth in 2FA relative to our last report. The move from 2.3% of our active users in the previous reporting period to 2.5% of our active users in the current period represents an 8.7% increase compared to the previous reporting period. Overall 2FA adoption remains relatively low, which is an unfortunate challenge across the industry. When accounts do not enable 2FA, we are left relying on less robust mechanisms to help keep Twitter accounts secure. We are, however, encouraged to see a significant increase in 2FA usage over the reporting period since it shows that people are increasingly utilizing 2FA to protect their Twitter accounts.
Security keys, while the most secure form of 2FA, are still relatively new. Twitter has made numerous improvements to our security key support over the past year, and we hope to see the usage number grow in the next reporting interval.
Overall, these numbers illustrate the continued need to encourage broader adoption of 2FA, while also working to improve the ease with which accounts may use 2FA. Making 2FA methods simpler and more user friendly will help to encourage adoption and increase security on Twitter.
