It seems like everyone is using a password manager these days. If you’re a Linux administrator, well you’re not left out. There’s a command line password manager called Titan which allows you to manage passwords that you administer. No more scribbling your password credentials on pieces of paper or placing them on insecure note applications on your desktop. You can now save your server credentials via the command line. You can recall them at anytime and even generate passwords for you. One thing it will not do is work on browsers like LastPass. Titan is strictly on passwords that you use via the command line.

Hacking a Tesla car from the Android phone is possible:
Hacking a Tesla is a thing we’ve seen before, but this time a team of security researchers at company Promon managed to locate, unlock, and steal a car using just an Android app. Every Tesla model comes with a companion smartphone application for Android and iOS that allows owners to do basic things such as checking the battery level and the charging status, locate the vehicle, and flash the lights to find it in the parking lot. And while these certainly come in handy, they can also be used by hackers to drive away by simply compromising the Android application.
