Password

Program Menu > Password

Temprecord loggers can be protected with a password (actually a "pass-phrase") - this can be any combination of letters, digits and punctuation characters (including spaces) up to 32 characters).

Password and Pass-phrase - what's the difference? No difference really, except your passphrase can include spaces, as can any encryption or hash key you provide to protect your datafiles.

Temprecord loggers can also be supplied to customers in a "locked" state. A locked logger will show a small padlock overlay on the picture of the logger shown on the summary tab. This "locking" is independent of any pass-phrase in the logger.

If a logger password has been set, it is not possible to edit the parameters, stop, or reuse the logger.

If you enter the digit zero (0) as the password, this is equivalent to no password, and anyone will be able to alter the user data, start delay or sample period.

The pass-phrase is case-sensitive, and leading and trailing spaces are ignored (but embedded spaces are not ignored). So the pass-phrases:

My Password

MY PASSWORD

my password

are all different. Be careful when typing (and remembering!) your pass-phrases.

The password will not display as you type it. You must enter the password twice, once in the 'Password' field, and again in the 'Confirm' field. These two passwords must match. You do not need to specify a minimum number of characters, but obviously the more the better.

Passwords should be easy to remember, and difficult to guess.

If you leave both the password fields blank, the current password will not be changed.

WARNING! Do not forget your pass-phrase!

If you do, you will be unable to alter the user data, start delay or sample period, stop the loggers, and in the case of the Multi-trip and Scientific models, and the Mon-T and LCD loggers, you will be unable to reuse them. You can still start or stop these loggers using the button if start with button or stop with button respectively have been enabled.

Temprecord are unable to reset passwords or determine what they have been set to. A logger with an unknown password can still be read, but it cannot be reused.

When you have entered all the data you wish to alter in the Program/Parameters form, click on 'OK' to update the user data and exit the form.

Click on 'Apply' instead if you want to update the user data in the logger, and not exit the form. This can be useful where you have several loggers to set up, each with the same or similar user data.

Once the logger has been started, you cannot alter the user data, password, start delay or sample period. Check that these are correct before you start the logger.

Removing a Password

To remove or clear a password, i.e. to allow anyone to access the logger without a password, edit the parameters, then enter a value of 0 (zero) into the password and confirm fields. Then save the parameters to the logger as normal and the password will be cleared. If the password and confirm fields are both blank when the parameters are saved, the password is not changed.

Earlier releases of the Temprecord software only allowed numeric passwords to be used. This restriction has been removed for all loggers, and pass-phrases up to 32 characters can be used with Temprecord Mk3, Mon-T and LCD loggers.

Mk3 and Mon-T loggers that have had their passwords set using earlier versions of Temprecord (version 5.xx and earlier) will still function correctly when read with the newer versions of Temprecord - they will accept the same numeric password as before. If the logger has the password altered with the newer version of Temprecord (version 6.xx and later) however, you will be unable to carry out any of the operations that require a password with the earlier versions of Temprecord.
