Security Alert: Update to the Authy Android (v25.1.0) and iOS App (v26.1.0)

Twilio believes that the security of our products and our customers’ data is of paramount importance and when an incident occurs that might threaten that security, we tell you about it.

Twilio has detected that threat actors were able to identify data associated with Authy accounts, including phone numbers, due to an unauthenticated endpoint. We have taken action to secure this endpoint and no longer allow unauthenticated requests. 

We have seen no evidence that the threat actors breached Twilio’s systems or that they obtained access to Twilio's systems or other sensitive internal data. As a precaution, we are requesting that all Authy users update to the latest Android and iOS apps for the latest security updates. While Authy accounts are not compromised, threat actors may try to use the phone number associated with Authy accounts for phishing and smishing attacks; we encourage all Authy users to stay diligent and have heightened awareness around the texts they are receiving.

This latest update addresses bug fixes, which include security updates. Please click on the link to download the latest version: 

We know the security of our systems is an important part of earning and keeping your trust. We sincerely apologize that this happened. The Twilio Security Incident Response Team will post any updates here if there are any changes. If you have further questions, please reach out to your Technical Account Manager or our Support team.

Notice: If you cannot access your Authy account, we recommend you immediately contact Authy support. One of our specialists will respond to your request, and work with you to get your Authy account back up and running again.
