mObywatel users must update the app to version 4.93.1 by 16 November 2026

The deadline and the reason for it

The mObywatel app must be updated to version 4.93.1 or a later release by 16 November 2026. The requirement follows the renewal of a certificate the app uses, a task carried out by the Ministry of Digital Affairs (Ministerstwo Cyfryzacji). The certificate is linked to the app's secure operation and its communication with state infrastructure. The ministry says the change is meant to keep the app and the services within it working correctly. The requirement covers Android phones and iPhones alike, and it also applies to mObywatel Junior, the version intended for children, so parents should check the app on their children's phones too. The official notice describes certificate renewals as a regular step that helps keep users secure.

Who has to act

Users with automatic updates switched on do not need to do anything, because the phone installs the new version by itself. Some of them may already have it, but the articles advise checking before 16 November. Those who have disabled automatic updates, or whose phone has not installed new versions for a long time, should check manually. To do this, open the app, tap the 'More' ('Więcej') tab, then choose 'Other' ('Pozostałe') and 'About the app' ('O aplikacji'). The version number also appears in the bottom right corner of the login screen. If it reads 4.93.1 or higher, no action is needed; if it is older, search for mObywatel in Google Play on Android or the App Store on iPhone and select 'Update' ('Aktualizuj').

What happens if the deadline passes

Missing the deadline will not cost users permanent access to the app. From 16 November, however, a user who tries to log in with an outdated version will see a message asking them to install a newer one. Without the current version, using all of the app's functions may become harder. Failing to meet the requirement may also lead to problems with electronic services accessed through the app.

Changes for businesses and institutions

The certificate for the mobywatel.gov.pl domain is also due for renewal on 16 November, which matters for businesses and institutions that use services under that domain, such as api.mobywatel.gov.pl. Such organizations should check how they integrate with the system, since extra steps may be needed where their solutions use, store or verify that specific SSL certificate. The change does not require modifications on the BackSystem, Tools or CryptoSystem side. Organizations that rely on the domain should therefore focus their checks on the integration points that depend on the certificate itself.
