When managing multiple lots in a co-ownership or tracking rental receipts from a phone between two appointments, even the slightest friction on an online client space turns into a real loss of time. MyCitya, the Citya Immobilier portal for tenants, co-owners, and landlords, is preparing a series of updates for 2026 that directly address these daily irritants.
Authentication, alerts, energy monitoring, technical reliability: let’s take stock of what is changing concretely.

Phishing and MyCitya Security: Reflexes to Adopt Before Any New Features
Before even discussing new functionalities, a ground-level issue deserves attention: phishing attempts targeting Citya clients are multiplying. Emails mimicking the MyCitya interface are circulating, inviting users to “confirm their credentials” via a fraudulent link.
The recommendations shared by several specialized sites are clear: never connect to MyCitya via a link received by email. Always go through the official address, typed manually or saved as a favorite. Using a password manager allows for automatic verification that the domain matches that of Citya.

This context gives full meaning to the unification of identifiers planned for 2026. A single login/password pair for all services of the Arche group (insurance, work, brokerage) reduces the exposure surface. Fewer accounts to manage means fewer weak or reused passwords.

Unique Arche Identifier and SSO: Concrete Impact on MyCitya Connection
The Single Sign-On (SSO) tested in agencies for several months aims for a simple goal: connect once, access everything. Co-ownership, rental management, insurance space, everything goes through a unique identifier linked to the Arche ecosystem.
In practice, migration requires each user to link their old accounts to this new identifier. The pilots conducted in agencies have shown that the procedure involves identity verification (email + proof of identity), followed by an automatic merging of accesses.
What This Changes in Daily Life
For a landlord managing three lots across two Citya agencies, the current situation sometimes requires distinct identifiers. With SSO, a single dashboard groups all properties and financial flows. You can switch from one lot to another without disconnecting.
Feedback varies on this point, with some pilot users reporting delays in the effective merging of their accounts. The generalization in 2026 should smooth out these initial frictions.
MyCitya Alerts and Notifications: Configuration by Event Type
Receiving a notification for every document submitted, every charge call, every general assembly minutes, can overwhelm the information. The 2026 update introduces a system of granular notifications on MyCitya, configurable by category.
For example, you can activate alerts only for:
- Fund calls and charge adjustments, to not miss any payment due
- Technical interventions reported on common areas, useful when monitoring an ongoing claim
- Regulatory documents submitted (collective DPE, minutes of AG), without being cluttered by commercial notifications
This sorting prevents users from disabling all alerts out of fatigue, which is the most common reflex when the volume of notifications becomes unmanageable.
Monitoring DPE and Rental Restrictions on MyCitya
The regulatory timeline on energy-inefficient homes is tightening. The most energy-consuming housing faces progressive rental restrictions between 2025 and 2028. For a landlord, losing sight of the DPE label of a lot risks renting out a property that has become non-compliant.
MyCitya will integrate in 2026 a module that displays the DPE label of each lot directly in the landlord dashboard. An alert is triggered when a lot approaches the rental prohibition threshold.
Energy Documents in Co-Ownership
For co-owners, the dedicated space now hosts documents related to the collective DPE and the tertiary decree. These include:
- The collective DPE of the building, with its date of completion and validity
- The action plans voted in AG to improve energy performance
- The compliance certificates with the obligations of the tertiary decree, when the building is concerned
These documents were previously scattered among the manager, the property managers, and regulatory platforms. Their centralization in MyCitya simplifies monitoring without multiplying contacts.
Technical Reliability of MyCitya: A Subject as Strategic as the Features
Reports of outages and bugs on MyCitya are now monitored in real-time by independent monitoring services. Documented outage spikes show that the stability of the platform remains an ongoing project, not a given.
The most frequently reported issues concern connection (blank page, redirect loop) and document display on mobile. The interface overhaul planned for 2026 specifically targets these two points, with a redesigned navigation for small screens and optimized loading of large attachments (AG minutes, accounting annexes).
For users who rely on MyCitya daily, checking the service status before attempting a failed connection helps avoid wasting time searching for a problem on the browser side when the outage is on the server side.
All these developments place MyCitya in a logic of consolidation rather than piling up functionalities. Unified authentication, targeted alerts, integrated regulatory monitoring, and enhanced technical stability form a foundation that addresses the real constraints of tenants, co-owners, and landlords in 2026.
