Customer Account Linking Consent Form for Single Sign-On

Streamline Customer Account Linking with GDPR-Compliant Consent Forms

In today's connected digital landscape, offering single sign-on (SSO) functionality across multiple platforms has become essential for delivering seamless customer experiences. However, when operating within the EU or processing data of EU residents, any account linking that involves data sharing requires explicit, informed consent under GDPR regulations.

This Customer Account Linking Consent Form template is designed for businesses implementing SSO solutions across multiple platforms, services, or applications. Whether you're a SaaS provider expanding your product ecosystem, an eCommerce business integrating marketplace platforms, or a digital agency managing client portals, this template ensures you collect legally compliant consent while maintaining transparency with your customers.

Built for GDPR Compliance and Transparency

The template clearly discloses what data will be shared across linked platforms, how it will be used, and what rights customers retain. It includes specific sections for scope disclosure, allowing you to detail exactly which platforms will be connected, what personal data categories will be shared, and the legal basis for processing. This level of transparency isn't just good practice—it's a GDPR requirement that builds customer trust and reduces compliance risk.

Streamline with Paperform and Papersign

Using Paperform's conditional logic, you can customise consent options based on which platforms customers want to link, showing or hiding relevant data sharing disclosures dynamically. Once submitted, you can route the consent record through Papersign to capture a formal eSignature, creating an auditable trail that demonstrates valid consent was obtained—essential for GDPR compliance audits.

With Stepper workflow automation, each consent submission can trigger your customer data systems to update permissions, sync the linked account status across platforms, and store the consent record in your compliance database. You can also set up automated reminders for consent renewal if your data processing activities change, keeping you GDPR-compliant without manual overhead.

This template is ideal for legal teams, compliance officers, IT departments, and product managers in software companies, digital platforms, fintech services, and any business operating under EU data protection regulations. By implementing clear, compliant consent collection from the start, you protect your organisation while delivering the connected experiences customers expect.
