Create new iOS code signing certificates (via cert)
cert is part of fastlane: The easiest way to automate beta deployments and releases for your iOS and Android apps.
In the gif we used
cert && sigh, which will first create an iOS code signing certificate and then a provisioning profile for your app if cert succeeded.
Note: It is recommended to use match according to the codesigning.guide for generating and maintaining your certificates. Use cert directly only if you want full control over what's going on and know more about codesigning.
This will check if any of the available signing certificates is installed on your local machine.
Only if a new certificate needs to be created, cert will
- Create a new private key
- Create a new signing request
- Generate, downloads and installs the certificate
- Import all the generated files into your Keychain
cert will never revoke your existing certificates. If you can't create any more certificates, cert will raise an exception, which means, you have to revoke one of the existing certificates to make room for a new one.
You can pass your Apple ID:
fastlane cert -u email@example.com
For a list of available commands run
fastlane action cert
Keep in mind, there is no way for cert to download existing certificates + private keys from the Apple Developer Portal, as the private key never leaves your computer.
fastlane action cert to get a list of all available environment variables.
Fastfile to contain the following code:
lane :beta do cert sigh(force: true) end
force: true will make sure to re-generate the provisioning profile on each run.
This will result in sigh always using the correct signing certificate, which is installed on the local machine.

It will show you
mobileprovision files like this:
cert # alias for "get_certificates"
get_certificates( development: true, username: "firstname.lastname@example.org" )
||Create a development certificate instead of a distribution one||
||Create a certificate even if an existing certificate exists||
||Your Apple ID Username||*|
||The ID of your Developer Portal team if you're in multiple teams||*|
||The name of your Developer Portal team if you're in multiple teams||*|
||The filename of certificate to store|
||The path to a directory in which all certificates and private keys should be stored||
||Path to a custom keychain||*|
||This might be required the first time you access certificates on a new mac. For the login/default keychain this is your account password|
||Set the provisioning profile's platform (ios, macos)||
* = default value is dependent on the user's system
To show the documentation in your terminal, run
fastlane action get_certificates
