Frequently Asked Questions

1) Why is the Secret Sign more effective than the Password?

If the Password is known (or can be guessed) by an impostor, the system is compromised with 100% certainty. If the Secret Sign is known (or can be guessed) by an impostor, it is still extremely difficult to reproduce the sign in the same manner as the legitimate author.
Unlike the Password, the Secret Sign does not need to be entered via the keyboard icon. So, it is much easier to enter than an 8-character, case-sensitive Password.
The Secret sign is much more easily remembered than an 8-character, case-sensitive Password and does not need to be changed if the Password is changed.
The Password released by the Secret Sign can be changed at any time without the need to remember the old Password.

2) Why is it important to back up my data before installing PDA-Protect?

If the installation sequence is not followed correctly, prior to and during installation, it is possible that you may be faced with a hard reset. If the data are backed up it is easy to return to the original state and recommence installation.

3) Why is it important to remove Password protection before installing PDA-Protect?

If you have set the Password from the Password icon in Settings/Personal, this record has to be removed before setting the new password from PDA-Protect. Failure to follow this procedure may result in the need to perform a hard reset which will erase all data and programs.

4) Why is it important to complete the Owner Information and bring the screen up when the device is turned on?

If the device is lost it provides the finder with the opportunity to return it to you.

5) Do I need to remember the Password I set at Registration?

You will need to enter the Password at the next ActiveSync (after you have gained access to your computer) This is one reason why it is important to make a note of the password and store it in a secure place, adjacent to your computer but not on the person. If you check the “Remember Password® on your computer you will not need to enter it again, unless you decide to uninstall the PDA-Protect software from the Pocket PC. If you cannot remember the Password it at any time you can change it to a new one (after you have submitted the Secret Sign) without having to enter the old Password.

6) What happens if I cannot gain entry at power-up when I submit my Secret Sign?

PDA-Protect can be Uninstalled after synchronization with the Partnership PC.

7) Why do I need to register my Authentic Signature?

This becomes part of the Crypto-Sign template and future software releases may use it as an electronic signature to be released to a transaction or document after a successful match against the Secret Sign template.

8) When I power up my device, sometimes I am not asked for a Secret Sign

Perform a soft reset in case this was not performed after installation.
Inspect the value of the PDA-Protect setting “Prompt if Device is powered off for more than.® If it is set to (say) 1 hour and the device is constantly switched off (automatically or manually) and on, with off-intervals less than 1 hour, then no Sign will be prompted.
Set the time interval to a setting which reflects your frequency of use and which ensures you are prompted for a Secret Sign as often as you are comfortable with.

9) Sometimes the PDA-Protect screen does not appear correctly and the unit does not allow me time to enter my sign or it powers down before I can do so.

This happens if the unit is powered off while the dialogue box is requesting a secret sign and left off for about 12 hours. The user should perform a soft reset to clear this condition.

10) What Action should I take after three Crypto-Sign mismatches?

Start with the action as a power down with the fail count reset to zero.
When you are comfortable with this action move to power down with fail count decremented by one.
When you are comfortable with this, if you are in a high risk scenario you may want to set the highest protection level (hard reset) but you should ensure you back up your data first.
