However, it’s crazy that dark mode hasn’t been added in 2025. I would rather use LastPass Authenticator if it were an option. ### 3/5 — Three years since last update and no dark mode + iOS 18 compatibility issues? *2024-12-17* It’s 2024 and your killing us with blinding white screens at night. Is it really that hard to add a small conditional style change? Maybe consider just scrapping this app and tell clients to use LastPass Authenticator. Update, it crashes frequently on iOS 18. Fix this! ### 1/5 — Crashes immediately after opening *2024-11-22* I get my push notification - and the app crashes as soon as I open it. Sometimes I can manage to hit the approved button quickly enough to approve the push, but most of the time not. Please fix. ### 3/5 — Three years since last update and no dark mode? *2024-09-05* It’s 2024 and your killing us with blinding white screens at night. Is it really that hard to add a small conditional style change? Maybe consider just scrapping this app and tell clients to use LastPass Authenticator. ### 4/5 — Same problem crashing *2024-02-12* App worked fine for a year or more but crashed today without letting me use it. I deleted the app, redownloaded and reset my phone number, then resent 2fa and all good. Nature of iPhones i guess, apps get corrupted. ### 1/5 — App instantly crashes *2024-01-10* For whatever reason for the last 6 months or so the app instantly crashes when opened. Luckily the code shows for a split second so if I open it over and and over I can usually piece it together before it expires. ## Frequently asked questions about DoubleSafe ### What is DoubleSafe?
