Backing up and recovering 2FA tokens from FreeOTP

Backing up FreeOTP

Using adb, create a backup of the app using the following command:

adb backup -f freeotp-backup.ab -apk org.fedorahosted.freeotp

SonarQube

Persistent SonarQube installation with Docker.

First Installation

Install docker:

sudo apt update

bettercap webui from docker

create volume

docker volume create bettercap

bootstrap/update

Only run caplets.update the first time as every time the entire system caplets folder is replaced with the downloaded contents from github, overwriting your changes, such as the credentials, with default values. You can either backup your changes and restore them later in the system folder, or simply copy the changed caplet files in bettercap’s working directory, in which case they’ll be loaded before the ones installed system wide. https://www.bettercap.org/usage/
