Reviews
Twilio User Authentication & Identity reviews
Verified Reviewer
Senior Data Scientist
“Liked being able to access multi-factor codes from several devices if a phone is lost. Found the password terminology in the app confusing.”
Islam R.
Founder
“Liked that the authenticator is available on desktop. Found that it still relies on SMS verification, which the reviewer considered a security weakness.”
Bruce S.
Recruitment Professional
“Liked how easy it was to use and the level of security it provided. Found that backend issues sometimes caused delays.”
Megan G.
Marketing Coordinator
“Liked the organized account icons, cloud backup, and how easy it was to add new accounts. Found that the codes expire too quickly.”
Anthony R.
IT Technical Project Manager
“Liked the simple, lightweight app, QR code setup, and free sync across devices. Found that the desktop app shows account names differently from the mobile app.”
Rafael P.
Undergraduate Finalist Student
“Liked that codes sync across devices and that the app is protected by biometric login and a master password. Found the interface basic, with some app logos missing.”
Simon M.
Creative Head
“Liked the easy setup, automatic backup and sync between devices, and fingerprint login for quick access to codes. Noted no major drawbacks.”
Ho'omana Nathan H.
Visiting Assistant Professor
“Liked the clean interface, how easily accounts moved to a new device, and a desktop app that is practical to use. Noted no major drawbacks.”
Gabriel B.
Software Developer
“Liked multi-device support and cloud backup protected by strong encryption. Found that it lacks push approval notifications like those in Microsoft Authenticator.”
Andrea V.
Artista Textil
“Liked how easy it is to use, that it works with many sites, and account recovery. Noted no major drawbacks.”
Tania Marcia D.
Agente II
“Liked that it is secure and easy to use once installed. Found installing and reinstalling it on new devices difficult.”

Sr. Manager of L&D
“Liked that the authenticator is simple and straightforward, making everyday two-factor logins quick without extra steps or confusion. Noted no major drawbacks.”
Suleman A.
Principal Software Engineer
