I am looking into adding more to my phone to better protect myself and my privacy. What would you consider some of the best apps for this purpose? I am not looking for any particular security app just general security that deals with having my phone online or in-use on a network.
Malwarebytes is a good app for phones that protects against malware threats as well as ransomware which is becoming more and more common.
Signal is a messaging app that encrypts all of your messages which is huge when it comes to privacy. It is better to use this than the built in messaging app on your phone.
Authy is a 2FA app that can better protect your accounts online by requiring every login to require a pin code that is auto-generated.
You honestly don't need anything if you are just careful with what you do on your phone. I would use a VPN whilst on public networks however and if you already use 2FA on your computer, you likely already have an app for that on your phone.
