Shopify Legacy Customer Accounts Sunset Timeline

Understanding the Shopify Legacy Customer Accounts Sunset timeline is essential to avoid disruption.

Why the Shopify Legacy Customer Accounts Sunset Matters?

The Shopify Legacy Customer Accounts Sunset impacts multiple areas of your business:

• Customer login experience
• Store security
• Conversion rates
• App compatibility
• Long-term scalability

Merchants who delay migration risk falling behind in both performance and security standards.

Passwordless Login: The Future of Shopify Customer Accounts

Perhaps the most transformative change in the new system is the move towards passwordless authentication. We have all experienced the frustration of “Forgot Password” loops.

One-Time Passcode (OTP) Login

Customers now log in using a secure one-time passcode (OTP) sent to their email.

This eliminates:

• Password creation
• Password storage risks
• “Forgot password” friction

Improved Security

Passwordless login protects against:

• Credential stuffing attacks
• Data breaches from reused passwords
• Unauthorised account access

Better User Experience

• Faster login process
• No password resets
• Reduced checkout friction
• Improved mobile usability

For merchants, this leads to higher conversion rates and stronger customer trust, especially when combined with strategies like user-generated content that reinforce buying confidence.

Built-In B2B and Store Credit Features

The new system introduced after the Shopify Legacy Customer Accounts Sunset is not just an upgrade it is a growth enabler.

Unified Customer Dashboard

Customers can now:

• View order history
• Access B2B pricing
• Manage company profiles
• Track store credit balances

Native Functionality (No Workarounds)

Previously, merchants relied on third-party apps for:

• Wholesale pricing
• Loyalty programmes
• Store credit systems

Now, these features are built directly into Shopify, offering:

• Better performance
• Lower maintenance
• Automatic updates

Flexible Customisation with Shopify App Blocks

The new system replaces rigid legacy structures with modern App Blocks.

No-Code Customisation

• Drag-and-drop editing via Shopify Visual Editor
• No need for Liquid or custom CSS
• Faster implementation for merchants

Easy Integration with Apps

Merchants can integrate:

• Loyalty programmes
• Subscription tools
• Order tracking systems

Upgrade-Safe Architecture

Customisations built using App Blocks:

• Remain stable after platform updates
• Reduce dependency on developers
• Improve long-term scalability

This makes the new system significantly more flexible compared to legacy accounts.
