Is 2FA via mobile phone still a good idea when phones are the most exposed device?

Everyone knows that two factors are better than one. My problem is that often the only second factor allowed is text messages to your mobile phone. This creates two concerns:

1) I travel frequently overseas and lose access to 2FA accounts any time the associated SIM card can’t touch a network.

2) Your phone is inherently your least secured device. I install way more software and download way more files on my phone than anywhere else with much less ability to verify sources or control access. For example, nearly every app requests sweeping permissions to function correctly. Even apps that aren’t granted explicit permissions have been found to backdoor those permissions through google services.

I feel like linking my phone to sensitive accounts (such as banking) would actually make them more exposed to attack and more difficult to maintain legitimate access.

Anti-Theft Mobile CPU

The newest Android phones use the Qualcomm Snapdragon 855 chipset with its TrustZone/TEE. The Android OS makes sure that a stolen phone, in its assembled form, is not usable.

Does Trustzone further prevent the CPU from being removed from a stolen phone and used in any way? I see how Qualcomm could lock the CPU (e.g., with a PIN or a fingerprint), but I also see how this could be dangerous for hardware development so I suspect that Qualcomm would allow some reset/unlock mechanism.

I’m basically wondering if there is any phone with anti-theft features preventing the CPU from having any stolen value. If not Android, what about iPhone?

Should I have own mobile app for .app extension domain name?

I have a plan to buy .app extension domain name ( But, I don’t have any mobile app for that website. Is that really important to have an app for .app extension website?

These success stories lists have their own mobile app also. Thats why I am asking. Is mobile app really needed for website?

Is Progressive Web Apps accessible only from mobile, how to deploy

Hey guys,

Have you ever heard about Progressive Web Apps? I just hear about it today and I scoured every web corner to understand what it is. The information is so scant.

All I know is it's standalone app on the web and accessible via mobile.

The example of this feature is

It cannot be accessed via desktop. Data on the web seems to fetch instantly once you tap on the link.

Do you have any idea how to they deployed it.

Mobile – Best way to dynamically add more fields to the form

I have a form so the user can issue an invoice, it is basically composed of comboboxes and 90% of the time the user will send the receipt with only one product, but rarely it will send with more than one, my question is whats the “best way” I can add a button or something so the user can add (and remove) more products to the receipt.

My current form:

Mobile Code Scanning

I know that MobSF is generally well recommended as the OSS solution for code scanning of mobile devices.

To my knowledge though, it only performs dynamic analysis of android applications (and you need genymotion?). Is there any tool that i could use to supplement MobSF, and provide dynamic analysis for iOS applications. This would prefer to be automated, but if some manual effort is required that would suffice.

Any options would be awesome!

Is the default orientation for mobile devices hardware or software specific?

I have noticed that when switching between one mobile application to another, sometimes the orientation of the user interface changes so that I have to rotate the screen 180 degrees so that it is facing the right way. I assume that if the software or hardware recognizes the direction that the user is holding the device, or at least the orientation that the most recent application is set at, then it should not change the orientation.

This leads me to wondering if there is actually a default orientation for devices which is configured in the hardware, and if there is also some configuration of the software as well (and that they sometimes are configured to unintentionally clash).

Is there are default orientation in landscape view for mobile devices? And if so do they exist in hardware and/or software configurations?
