About the card New card issues Card operation



What is an OTP card?

The OTP card is a One Time Password generator. When the code button is pushed a new dynamic password is displayed on the card.

The card is based on event-synchronous dynamic password system. The cryptoalgorithm incorporated in the card uses a counter that stays "in sync" with the server based on the number of passwords generated.

The OTP card rely on the synchronizing of an event between the card and the server (which is the generation of the dynamic password). The dynamic password is more secure because it can only be used once. This delivers a much higher level of security than memorized passwords (which can be easily stolen).

Youíll be able to use your OTP card only after you complete a registration and activation process on our site. The card is personal and cannot be shared.



Who needs a card?

VPN users (Samba VPN/VPN Client/WebVPN)

The VPN services solve a problem of users, that need restricted Internet services from the university (e.g. e-journals), but don't connect directly to HUJI network and already have an existing connection to a different network/ISP.

NOTE: Tango VPN reqires an OTP card only for services OTHER than Internet, mail and SSH.

Once you've activated your OTP card, the OTP password replaces automatically your 4 digits personal code. Accessing central information systems sites (such as grades and budgets), will require an OTP password.

An OTP card can be purchased at the Microshop, tel. 026584217. The card can be purchased only through university budgets.

Finance Information units, Students of the School of Engineering and Computer Science) does not need to purchase a card.

How to use the card

Choose a category:


Basic usage

You will use only 2 keys:ON/OFF andCODE:

  • ON/OFF - Press to turn on the card. The hand icon will appear on the card's display.
  • CODE - Press to generate a password. The password will appear on the card's display.

If you press accidentally on other keys and can't generate a password, turn the card off and on again.


The Password

The generated password is only a part of the OTP password. When asked to provide a password - type first the Activation code obtained during the card activation, and then (no spaces) the generated password that appears on the card's display.

The generated password's range of letters and numbers is 0-9 and a-f. Always type the password in lower case (even if a letter in the cardís display appears in caps). Use the following examples to avoid possible confusions:

= zero   = 1
= b = 6


The Bar code

The Bar code is the card's ID. It appears on the rear of the card. You will need it during the activation process, card cancellation and for other support issues. In the example below the barcode is: 20047269 (no spaces).


Battery problems

When a battery icon appears on your card's display you should immediately turn off the card.
Do not use the card until the battery is replaced!

If you continue using the card, the damage will be irreversible and you will need to purchase a new card.

Replacing the battery
To replace a battery remove the screw from the rear of the card, slide the battery drawer out and install the new battery (see the above image). A new battery can be obtained within a 1-year warranty at the Academon (model: CR2025)
