TOTP Token

class privacyidea.lib.tokens.totptoken.TotpTokenClass(db_token)[source]

Create a new TOTP token object from a DB Token object


db_token (orm object) – instance of the orm db object

check_otp(anOtpVal, counter=None, window=None, options=None)[source]

validate the token otp against a given otpvalue

  • anOtpVal (string) – the to be verified otpvalue

  • counter – the counter state, that should be verified. For TOTP

this is the unix system time (seconds) divided by 30/60 :type counter: int :param window: the counter +window (sec), which should be checked :type window: int :param options: the dict, which could contain token specific info :type options: dict :return: the counter or -1 :rtype: int

check_otp_exist(otp, window=None, options=None, symetric=True, inc_counter=True)[source]

checks if the given OTP value is/are values of this very token at all. This is used to autoassign and to determine the serial number of a token. In fact, it is a check_otp with an enhanced window.

  • otp (string) – the to be verified otp value

  • window (int) – the lookahead window for the counter in seconds!!!


counter or -1 if otp does not exist

Return type


desc_timestep = 'Specify the time step of the time-based OTP token.'
static get_class_info(key=None, ret='all')[source]

returns a subtree of the token definition

  • key (string) – subsection identifier

  • ret (user defined) – default return value, if nothing is found


subsection if key exists or user defined

Return type

dict or scalar

static get_class_prefix()[source]

Return the prefix, that is used as a prefix for the serial numbers. :return: TOTP

static get_class_type()[source]

return the token type shortname



Return type


classmethod get_default_settings(g, params)[source]

This method returns a dictionary with default settings for token enrollment. These default settings are defined in SCOPE.USER or SCOPE.ADMIN and are totp_hashlib, totp_timestep and totp_otplen. If these are set, the user or admin will only be able to enroll tokens with these values.

The returned dictionary is added to the parameters of the API call. :param g: context object, see documentation of Match :param params: The call parameters :type params: dict :return: default parameters

static get_import_csv(l)[source]

Read the list from a csv file and return a dictionary, that can be used to do a token_init.


l (list) – The list of the line of a csv file


A dictionary of init params

get_multi_otp(count=0, epoch_start=0, epoch_end=0, curTime=None, timestamp=None)[source]

return a dictionary of multiple future OTP values of the HOTP/HMAC token

  • count (int) – how many otp values should be returned

  • epoch_start – not implemented

  • epoch_end – not implemented

  • curTime (datetime) – Simulate the servertime

  • timestamp (epoch time) – Simulate the servertime


tuple of status: boolean, error: text and the OTP dictionary

get_otp(current_time=None, do_truncation=True, time_seconds=None, challenge=None)[source]

get the next OTP value


current_time – the current time, for which the OTP value

should be calculated for. :type current_time: datetime object :param time_seconds: the current time, for which the OTP value should be calculated for (date +%s) :type: time_seconds: int, unix system time seconds :return: next otp value, and PIN, if possible :rtype: tuple

static get_setting_type(key)[source]

This function returns the type of the token specific config/setting. This way a tokenclass can define settings, that can be “public” or a “password”. If this setting is written to the database, the type of the setting is set automatically in set_privacyidea_config

The key name needs to start with the token type.


key – The token specific setting key


A string like “public”

property hashlib
previous_otp_offset = 0
resync(otp1, otp2, options=None)[source]

resync the token based on two otp values external method to do the resync of the token

  • otp1 (string) – the first otp value

  • otp2 (string) – the second otp value

  • options (dict or None) – optional token specific parameters


counter or -1 if otp does not exist

Return type


property timeshift
property timestep
property timewindow
update(param, reset_failcount=True)[source]

This is called during initialization of the token to add additional attributes to the token object.


param (dict) – dict of initialization parameters
