    Compliance with PSD2 financial regulations

    Ideally, finding a security solution that is ahead in its development and proactive to any new regulations about to be introduced into the market will prevent the need to find a new setup once new regulations are published. Otherwise, an institution has to cover significant costs each time a new regulation needs to be implemented.

    With SecSign ID all recent regulations for the financial sector are covered and all solutions are being managed proactively in regard to new regulations or new security achievements.

    The PSD2 regulations are the most recent development in the financial cybersecurity sector. SecSign has been compliant to all requirements long before the regulations became mandatory. We offer solutions that have been successfully tested and used in the market for years.

    PSD2 regulations at a glance

    Practical Implementation

    How does the implementation of PSD2 compliant setups look like in the day-to-day business? This is up to you.

    Compliance to the PSD2 regulations can be realized with your preferences and setup in mind. This includes design, authentication and rollout as some of the many options we offer custom solutions for.

    Transaction verification

    The verification of the transaction by the customer is cryptographically bound to the user by PKI-based authentication. The user verifies the transaction in the custom banking app or in the existing banking app by integration via SDK.

    Mode of operation

    The SecSignApp can initiate the authentication in two different ways.


    The app displays four random access pass icons. The user confirms the log-in by tapping at the icon which is displayed simultaneously in the online banking’s log-in page. The set of icons can be determined by the bank if preferred.

    Mode of operation

    The SecSignApp can initiate the authentication in two different ways.


    Alternatively, the app can just ask for confirmation without access pass icons. This mode is sufficient during a two-step-authentication where the user has authenticated to the online banking system with username and password already.

    Point of authentication

    Authentication for the user can be prompted with the initial login or only to access sensitive data and actions, like money transfers.

    The user authenticates during the initial login to the banking service. All user activity is protected with two-factor authentication and the user has to authenticate each time he starts a session with the banking app.

    The user can login to his banking services with just his user name and password. If he wants to access sensitive areas and actions, for example a money transfer, he has to authenticate with the two-factor authentication.

    All options are available for mobile banking and desktop banking

    Mobile First: Integration in mobile apps

    SecSign offers convenient integration in existing banking apps with our SecSign ID SDK to add two-factor authentication to you existing login and transaction verification system. No need to worry about the rollout and implementation of a whole new system, just add 2FA to your existing app and comply to all regulations in one simple step.

    Alternatively, we offer the option of a custom YourBank ID app build by our developers to fit your requirements and compliance to all important regulations. The YourBank ID app provides you with custom on-boarding procedures, corporate design and custom endpoint monitoring options. The design of the SecSignApp can be specified by the financial institution. The name of the app can be modified, for example MyBanklD.
    No need to hire any additional iOS or Android developers, SecSign offers the ready-to-go setup.
    Additionally, relevant information may be included in the app, for example contact addresses, telephone numbers and links to the existing apps.

    In both cases you can offer your users a convenient and secure two-factor authentication as well as signature and transaction verification options. The apps can be used to authenticate the user for you web login, mobile login and mobile verification of transaction.

    For users without a smartphone SecSign offers several alternatives for a secure authentication.

    Users without a smartphone can choose to authenticate via the SecSignApp for Windows 10 or OSX.
    Alternatively, the SecSign ID Server supports the authentication with one time passwords generated using the HMAC based one-time-password algorithm (HOTP).
    HOTP is a standard supported by a wide range of hardware tokens.
    The customer enters this OTP into the web site to complete the authentication. The SecSign ID verifies the OTP using a private key previously shared between the hardware OTP generator and the SecSignlD Server.
