How it works
Our ReuseID solution is comprised of three key components:
- Identity store
- Authentication
- Identity proofing (optional)
These components are fulfilled using different Signicat products, which are combined to create a solution for implementing your own reusable identity.
With ReuseID, you always get an Identity store and at least one Authentication method. These form the base of our ReuseID product.
Other Signicat products for Identity proofing can be optionally added and orchestrated to fit you needs for a reusable identity.
Combining products in ReuseID
Identity store
The identity store component is used to manage all of your end-users and store attributes such as those obtained from a successful identity proofing process.
Our identity store is flexible, which means that you can manage or update users in it with our API. Here, you can also add additional user attributes if required.
Authentication
The authentication component is the key to making your ReuseID users reusable. It enables continuous interaction with your end-users and helps to build long-term trust.
Once a user is created, their identity can be securely reused for authentication across your entire ecosystem. Use it for the likes of:
- Logging in
- Signing
- Authorising transactions
- Recovering to new devices
Authentication methods
ReuseID supports the following authentication methods:
- MobileID
- Passkeys
Both methods are secure and user-friendly; designed to deliver strong, seamless authentication experiences without the need for passwords, OTP codes, or unnecessary friction.
What is MobileID?
MobileID is strong customer authentication product from Signicat that allows you to authenticate your end-users using your mobile app. It offers a rich feature set, strong security, a seamless user experience and full PSD2 compliance.
We recommend that you use this authentication method if you have a mobile app or are pursuing a mobile-first strategy.
What are passkeys?
Passkeys are a modern and passwordless authentication method that allow you to authenticate your end-users within a browser.
We recommend that you use this authentication method if you interact primarily with your end-users in a browser and are looking to replace traditional passwords.
What authentication method should I choose?
For guidance on what authentication solution is best for your use case, you can use the table below:
| Question | MobileID | Passkey |
|---|---|---|
| Do you have a mobile app or mobile strategy? | ||
| Do you only need a browser-based solution? | ||
| Do you need to be PSD2 SCA compliant? | ||
| Do you want omni-channel support? | ||
| Do you want one solution for all markets? |
If you want both MobileID and Passkeys, then it is possible for you to combine them and use them in parallel.
Identity proofing
The identity proofing component is important for a reusable identity, as it allows you to:
- Verify the identity and collect attributes when creating a new ReuseID user.
- Perform a step-up identity verification for existing ReuseID users.
- Collect additional information for existing ReuseID users.
After a successful identity proofing process, ReuseID adds a set of attributes to the user. These attributes can be returned to you in the response upon a successful authentication.
The identity proofing component is an optional add-on to ReuseID. You can use one of our pre-defined flows, or we can create a custom flow to fit your requirements.
You can easily add identity proofing to your ReuseID by combining it with other Signicat products using one of our orchestration solutions. You can also orchestrate the flow yourself, with or without Signicat products.
ReuseID supports three options for conducting an identity proofing:
- Ready-made flows orchestrated by Signicat.
- Custom flows orchestrated by Signicat.
- Do-it-yourself flows orchestrated by you.
Ready-made flows
Our ready-made onboarding flows allow you to quickly roll out a full ReuseID solution, including identity verifications.
How to implement
Custom-made flows
If none of the ready-made flows fit your requirements, then we can help you design and build your own custom-made flows.
How to implement
Do-it-yourself flows
If you already have an identity proofing process in place, then you can keep that as is. ReuseID is flexible and allows you to create users and authentication methods without the identity proofing step.
You can manage the user's identity and set any user attributes at any time using our APIs.
