Validating the Security of the Seed Phrase During Device Backup

While the seed phrase itself isn’t backed up to the cloud, this test verifies that other app data doesn’t inadvertently contain clues about it. After an Android cloud backup and restore, the tester must scrutinize the restored MetaMask data for any information that could hint at the seed phrase or private keys. The app should not store any such information, even in an obfuscated form, in its standard data directory. The only way to restore the wallet must remain the manual entry of the secret recovery phrase. This final validation ensures that the security model is never compromised, even by system-level backup features. This absolute separation is a cornerstone of the wallet’s security philosophy, constantly reinforced in the materials on metamask. The test is successful if no sensitive information is recovered from the cloud backup.
