Now in this new model, I’ve also moved to a a new phone.., and thus I can’t open this app any longer. Effectively, I am locked out all my accounts where I depend on MFA. This is absurd, rendering this app not only useless but dangerous. Look elsewhere! ### 1/5 — Unable to import from old app *2025-07-30* I still have the old app, and this one is unable to import the data, it’s empty ### 1/5 — Less features but a nicer appearance? *2021-12-27* No control on accessing the app, no facial or passcode option to restrict access. Sections are larger with useless info added and no way to remove things like date added (who cares?) Generally looks like a designer got at it. Less useful but oh so pretty now! ### 2/5 — Not as secure as the original HENNGE OTP generator *2020-11-22* The software allows one to store all his OTP accounts in place place. It works well; does what it says and I never had a problem with it. Now, unfortunately, HENNGE Lock is replacing the “original” HENNGE OTP Generator, being phased out. Sadly a key component I relied upon, and arguably the biggest differentiator towards its competitors, was the ability to lock all OTPs with touch ID/Face ID/Numeric password. I mean, the original version boasted this feature while the new one doesn’t even bother to preserve (at least) the numeric password? Very disappointing to say the least. Probably amateurism. In a nutshell, whatever features this new app has, they are irrelevant if I cannot keep the OTPs secure. I am now looking for alternatives to HENNGE Lock, while with HENNGE OTP Generator it was all I wanted from an OTP storage. ## Frequently asked questions about HENNGE Lock ### What is HENNGE Lock used for?
