Authenticator Plus to andOTP Magiculator

The Authenticator Plus app seems to have been abandoned by the developer. andOTP is a decent, open source, alternative.

This converts the Authenticator Plus backup database into andOTP-compatible backup database that can be directly important into andOTP.

Installation

With Docker

Install Docker.

Without Docker

The only dependency is pysqlcipher3. On my machine, I installed it like this:

$ sudo apt install -y libsqlcipher-dev
$ git clone https://github.com/rigglemania/pysqlcipher3
$ cd pysqlcipher3
$ python3 setup.py build
$ sudo python3 setup.py install

Usage

With Docker:

$ git clone https://github.com/adiov/authplus-to-andotp-magiculator.git
$ cd authplus-to-andotp-magiculator
$ docker run -v ${PWD}:/authplus-to-andotp -it adiov/authplus-to-andotp-magiculator --database authplus.db
Authenticator Plus master password:
andotp.json is now ready.

Alternatively, you can also build the image locally.

$ git clone https://github.com/adiov/authplus-to-andotp-magiculator.git
$ cd authplus-to-andotp-magiculator
$ docker build -t authplus-to-andotp-magiculator .
$ docker run -v ${PWD}:/authplus-to-andotp -it authplus-to-andotp-magiculator --database authplus.db

Without Docker:

$ ./authplus-to-andotp.py --database authplus.db
Authenticator Plus master password:
andotp.json is now ready.

Notes

• This will decrypt the Authenticator Plus backup database and output the andOTP backup database in decrypted plain-text. Be careful how you handle that.
• This attempts to preserve the entries' icons/thumbnails by using the Issuer field as thumbnail, which doesn't have a 100% success rate, but should work most of the time.
• As far as I can tell, Authenticator Plus doesn't handle checksum algorithms other than SHA-1 or OTP digits other than 6. The output file will use those values by default. The only exception seems to be Battle.net TOTP with which Authenticator Plus uses 8 digits; this script attempts to preserve this info and pass it to andOTP.
