Certificates on iOS/iPadOS
To work with corporate certificates:
- Download the root and cross-certificates.
- Confirm the download when prompted “The website is trying to download a configuration profile. Allow?”.
- If there are multiple devices, select the device for installation.
- Go to Settings > Profile Downloaded > Install.
- Enable trust: Settings > General > About > Certificate Trust Settings > turn on the toggle for the installed certificate.
- Fully quit the app and start it again.
⚠️ The fifth step is mandatory. The app does not use a certificate without a trust mark, and you won't be able to connect to the server. This is the most common reason why “I installed the certificate, but it still won't sign in.”
If your organization's server has switched to Ministry of Digital Development National Certification Authority certificates, see the instructions.
