Documentation for this is incomplete. Contributions are happily considered!
Installation[edit]
Recommended to be installed inside an offline VM (vault). [1] When you want to keepassxc as replacement for Google Authenticator (actually TTOP, Time based One Time Password) Two Factor Authentication (2FA)) then a Debian based VM is more suitable than a Whonix-Workstation ™ based VM. [2]
Packages yubikey-personalization yubikey-personalization-gui are YubiKey related. Users not using YubiKey can skip installation of these packages and install keepassxc only.

keepassxc
First run question: either answer is ok.
Create a new database.
Default file name Passwords.kdbx is ok.
If you are using Full Disk Encryption you might want to use a very easy password. Up to you.
Left click one time on root
Then go to menu → entries → Add new entry → any name name as test → ok
right click on test → time based on time password → set up TOTP → Default → paste 2FA code → ok
right click on test again → time based on time password → show TOTP
Time Fix[edit]
2FA TTOP code changes every 30 seconds. So clock needs to be reasonable correct.
Troubleshoting only. If code does not match.
Set timezone to UTC for simplicity.
sudo cp /usr/share/zoneinfo/Etc/UTC /etc/localtime
Go to https://www.timeanddate.com/worldclock/timezone/utc [archive] or any other similar source to find out the time in UTC.
Fix the click. Change the date and time accordingly!
sudo date -s "26 SEPT 2018 11:54:25"
Check if the clock is correct now.

Footnotes[edit]
- ↑
- In Qubes, apt-get package installation could be done in TemplateVM.
- In Qubes, download and verification could be done in a temporary TemplateBased AppVM, ideally Qubes/DisposableVM. Then move to offline vault VM.
- In Non-Qubes-Whonix ™: install first, then disconnect internet and never re-enable internet access. TODO document
- ↑ Because accurate time required for TTOP and due to Boot Clock Randomization and sdwdate anonymizing time.
