You are trying to log in to MyCitya, the page is stuck in a loop, and your client area remains inaccessible. Since the interface redesign launched in 2026 and the unification of identifiers within the Arche group, this type of blockage affects an increasing number of users. Understanding where the problem comes from often allows it to be resolved in a few minutes, without going through customer service.
Unification of Arche identifiers: the hidden cause of MyCitya blockages in 2026
Most MyCitya connection guides still describe the old functioning. Since 2026, identifiers have been unified within the Arche group, which significantly changes the login process for clients linked to multiple entities or contracts.

Specifically, if you had an account linked to a Citya agency and another via a subsidiary of the group, your old identifiers may no longer work as they did before. The new interface requires a unique association. The previous password may still be valid, but the login (email address or numerical identifier) may have been merged or replaced.

If your login fails without a clear error message after April 2026, it is probably related to this unification. The first thing to try is to use the email address linked to your last active contract, and then initiate a password reset from the official page citya.com/mycitya.
MyCitya connection error: quick diagnosis based on the displayed message
Not all blockages come from the same cause. The message (or absence of a message) displayed on the screen guides the diagnosis.
Blank page or infinite loading
This behavior rarely points to a password issue. It is most often a conflict between the browser and the platform. Two reflexes to have:
- Clear the browser’s cache and cookies, then reload the page. On Chrome: Settings, Privacy, Clear browsing data. On Firefox: Settings, Privacy, Cookies and site data.
- Test with another browser or in private browsing mode. If the page displays, the problem comes from an extension or a corrupted cache on your usual browser.
- Check that your internet connection works on other sites. An unstable connection (weak Wi-Fi, saturated mobile network) can cause a timeout on the MyCitya platform without displaying an explicit error.
Message “incorrect username or password”
This message appears in two distinct cases. The first: a simple typing error, often related to case sensitivity or an extra space copied and pasted. The second, more frequent since the 2026 redesign, concerns migrated accounts whose identifier has changed.
Always initiate the “Forgot password” procedure before contacting your agency. The reset link is sent to the email address associated with the account. If you receive nothing (check your spam), it means the registered address is not the one you are using, or your account has not yet been migrated.
Message “account does not exist” or “no space found”
This blockage specifically affects users whose management mandate is no longer active. Access to MyCitya requires an active management mandate with a Citya agency. Without an active contract, the platform simply does not recognize the account. You cannot create a MyCitya access in self-service: it is the agency that links the client profile to one or more lots.
If your mandate is indeed active but the message persists, contact your Citya agency directly to verify the linking of your lot in the system.
MyCitya connection on mobile: specific traps to avoid
The MyCitya platform is accessible from a smartphone via the mobile browser. Feedback varies on this point, but several users report different behaviors between desktop and mobile access.
The first trap: the automatic password filling by the phone. After the migration of identifiers, the phone’s password manager often injects the old password without the user realizing it. Result: repeated connection failures, sometimes followed by a temporary account lock after several attempts.
To work around this issue, temporarily disable auto-fill, manually enter your identifiers, and remember to update the saved password once the connection is successful.
Second trap: the browsers embedded in applications (when you click on a MyCitya link from an email or messaging app). These embedded browsers poorly manage certain session cookies. Copy the address and open it in Safari or Chrome instead of the embedded browser of your messaging app.
Securing your MyCitya access after resolving the issue
Once the connection is restored, a few adjustments can prevent experiencing the same situation again.
- Update your email address in the account settings if the one registered is outdated. This is the only recovery channel for the password.
- Choose a password distinct from the one used on other sites, with at least a dozen characters mixing letters, numbers, and special characters.
- Note the exact identifier (email or number) used for the successful login. After the Arche migration, keeping track of the active identifier avoids future confusion.
- Check that your documents (receipts, management statements) are accessible from your client area. Partial access may indicate incomplete linking of your lots by the agency.
The majority of connection issues with MyCitya can be resolved without agency intervention, as long as you identify whether the blockage is technical (cache, browser, network) or administrative (migrated identifier, inactive mandate). For cases where the password reset yields no results and the mandate is indeed active, direct contact with your Citya agency remains the last resort, specifying the exact error message displayed on the screen.
