<h2>Additional fields</h2>
Some features defined in the RFC are not used yet in Google Autheticator.
<h3>Algorithm</h3>
OPTIONAL: The algorithm may have the values:</BR>
</BR>
    SHA1 (Default)</BR>
    SHA256</BR>
    SHA512</BR>
    MD5 </BR>
<h3>Digits</h3>
OPTIONAL: The digits parameter may have the values 6 or 8, and determines how long of a one-time passcode to display to the user. The default is 6.</BR>
<h3>Period</h3>
Defines a period that a TOTP code will be valid for, in seconds. The default value is 30.</BR>
The period parameter is no longer ignored by the Google Authenticator implementations. </BR>
<h3>Trim</h3>
This value is for "trimming" the time of the server. It can be positive or negative and is used if you can't change the server's time settings.
