You receive your temporary credentials by email or on a paper document, you log in for the first time on MyFoncia, and then: link expired, email address unknown to the system, password rejected. These blocks affect both tenants and co-owners, and they almost always occur within the first few minutes of account creation. Here’s how to anticipate them concretely.
Incorrect email address in the Foncia file: the invisible block
The majority of failures at the first connection do not come from a wrong password. The problem lies upstream: the email address registered by the agency no longer matches the one used by the client. An old account deleted, a typo during the lease signing, a professional address replaced since.

When entering your temporary identifier on the MyFoncia page, the system sends a validation email to the address listed in the file. If this address is incorrect or outdated, the email never arrives. You wait, check the spam, try again, without understanding that the problem is not technical but administrative.
There is no automatic procedure to change this address before account creation. The only solution is to contact your Foncia agency directly to correct the information, which can extend the activation time by several days. Before even attempting the first connection to MyFoncia my account, it is advisable to check with your manager that the registered email address is indeed correct.

MyFoncia activation link expired: restart without wasting time
Once the temporary identifier is entered, MyFoncia sends an email containing a confirmation link. This link has a limited validity period. The exact window is not publicly communicated, but it is described as short in the official Foncia guides.
The classic trap: you receive the email at the end of the day, think you’ll finish the registration the next day, and the link is already dead. You click, the page shows an error or redirects to the standard login page without a clear message.
In this case, you need to restart the procedure from the first connection page by re-entering the temporary identifier. A new validation email will be sent. This time, you complete the activation right away. Keeping a tab open and clicking on the link as soon as the email is received avoids looping on this scenario.
MyFoncia temporary identifier: where to find it based on your profile
The first connection identifier is not found in the same place depending on whether you are an owner, co-owner, or tenant. This is a frequent source of confusion, especially when managing multiple properties or having just signed.
- Landlord owners find their identifier on the latest management report sent by the agency.
- Co-owners find it on their latest call for funds, usually in a dedicated section.
- Tenants receive a welcome email upon signing the lease, which contains the temporary identifier. If this email has been deleted or filtered, they need to request a resend from the agency.
A useful reflex: archive this document or notification as soon as received. Once the account is activated, the temporary identifier is replaced by the personal email address and is no longer useful, but as long as the activation is not done, it is the only entry key.
Case of tenants without a welcome email
Responses vary on this point, but some tenants never received a welcome email, especially when the lease was signed at the agency without digital transmission. In this case, they need to call the managing agency and request either a resend of the email or the direct communication of the temporary identifier. No online form allows for recovering this identifier independently.
MyFoncia password rejected: criteria and common errors
After validating the confirmation link, MyFoncia asks you to create a permanent password. The criteria are strict: minimum six lowercase letters, one uppercase letter, and one digit. If any of these criteria are missing, the form rejects the password without always clearly indicating what the problem is.
Two common errors occur:
- Using a password that is too short, copied from a password manager set to a different security format.
- Forgetting the uppercase letter or the digit and interpreting the rejection as a bug on the site.
- Copying and pasting the password with an invisible space at the beginning or end of the string, which distorts the input.
Type the password manually, check that it meets the three criteria, and validate. Once the account is created, the email address becomes the permanent identifier for all subsequent logins.

Browser and MyFoncia mobile app: compatibility to check
Some blocks at the first connection are not related to the identifier or the password, but to the browser used. MyFoncia works on recent versions of major browsers, but outdated versions or ad-blocking extensions may prevent the login page from loading correctly or intercept the validation email.
Before contacting the agency, you can test with another browser or in private browsing. On mobile, the MyFoncia app offers a dedicated interface, but the first activation often needs to be done via the website before being able to log in from the app. Attempting to create your account directly from the app without having finalized the activation on the site can generate misleading error messages.
A final often overlooked point: clear the browser cache if the login page exhibits abnormal behavior after several attempts. Expired session cookies can maintain a blocked state on the client side, even if the account has been successfully activated on the server side.
