2FA: Replace Google Authenticator with KeePass and FreeOTP
Two Factor Authentication (2FA)
I guess most of the readers would get some serious problems if they loose access to their Google account or if another persons could gain access to this account. To avoid this, Google offers the possibility to secure the own account with a 2FA. My favorite is the TOTP mechanism which is used by the Google Authenticator app. I do not like this app and would like to replace it with FreeOTP and KeePass. This tutorial shows how to achieve this.
TOTP instead of Google Authenticator
The procedure can be started by using this link.
In this view we click on “Get started”. In the next step we must add our mobile phone number (if not already done). It can be removed after an other 2FA method is chosen.

In my honest opinion SMS is a bad idea: cellphone lost? Sim lost? No connection to the cellular network? This is way I want to use a method which also works offline. For this purpose I choose the “Authenticator App”:
After a click on “set up” I choose Android:
Google now shows us the secret which has to be inserted into KeePass or FreeOTP:
If no scanner is available just choose: “Can’t scan it?”
This “secret” must now be entered in FreeOTP or into KeePass:
Now you should be able to generate the TOTP keys and with that you can verify that 2FA is correctly ste up:
Step 4 (optional)
Now you can remove your mobile phone number from your google account:
First click on the pencil and then on “Remove phone”:
