You can export signer keys that you have imported or generated on Gnosis Safe Mobile. This is important, as Gnosis Safe Mobile does not provide any cloud syncing or another way to restore your signer keys in case your mobile device is inaccessible.
To export a signer key, navigate to
App Settings >
Owner Keys and select the signer key for which you would like to generate a backup.
After selecting a signer key, click
Export in the top-right corner.
You are then presented with a choice of displaying the seed phrase for this signer key or the raw private key. (If you have imported a signer key, you will only see the second option).
Please make sure your seed phrase or private key are securely stored, such as a password manager, for example.
