Frequently Asked Questions

What if a user's phone is lost or forgotten

If a phone is lost or temporarily misplaced, an administrator can easily login to our and revoke the lost phone or temporarily add a "spare" phone to the user's account until the original phone is found.

What if my phone dies?

If your phone dies, always plug it into the computer that you are using to charge it and continue using it for two factor authentication (2FA). For doors, you can use a backup option (e.g., a smartcard) if your company has them configured, ask a friend, or find a charging station.

Does the App drain my phone battery more?

In our tests we have seen no increase in battery usage, aside from having Bluetooth enabled.

Who is going to manage the platform?

Allthenticate will host all of the management software and your company can simply login to our web-based service to manage all of your resources and users.

How do I set it up?

Our door readers are completely backward compatible with existing infrastructure, and only require power, and Internet access (i.e., Ethernet or WiFi). We can either ship the devices pre-configured with your WiFi network, or you can configure them upon arrival. All 2FA solutions require the installation of our software and a browser extension.

Why doesn't SDA work after I reboot my machine?

If you have disk encryption enabled, the password is unfortunately required to decrypt the disk. In this case, you can login to your machine for the first time by declining the SDA request, and typing your password in manually. To check if you have disk encryption enabled, type:
ls -A /home | grep ecryptfs
If the directory .ecryptfs exists, you do have disk encryption enabled. ## Why does my Bluetooth keeping turning off and on? There is some strange thing that arises when the phone and the computer are paired. The only fix that we are currently aware of is to unpair the phone. To do this, first kill the SDA service:
sudo service sda-delegate stop
Then unpair the device in your Bluetooth Settings,

and restart the SDA service:

sudo service sda-delegate start

Why isn’t SDA working when I type sudo or try to unlock my machine?

This is likely because you have not selected a username, or usernames, to associate with SDA. Please configure this using our GUI, as shown below:

Why can’t I install SDA from apt-get?

If you are getting the following error:

The following packages have unmet dependencies:
 sda : Depends: sda-delegate-service but it is not going to be installed
       Depends: sda-pam-module but it is not going to be installed
       Depends: sda-websocket-service but it is not going to be installed
       Depends: sda-gui-config but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
it is because we require some packages from the universe/multiverse repositories. You can fix this by typing the following:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"

Why isn’t Bluetooth working?

If you just installed SDA on 18.04, it’s possible that the bluetooth service simply needs to be restarted:

service bluetooth restart
