Part 3/14:
Encrypted Cloud Backup: Using strong encryption, users can store backups on Google Drive (Android) or iCloud (iOS). To protect the wallet, users set a PIN, which encrypts the wallet file. The backup process creates a secure, encrypted copy that can be tested to ensure recoverability.
Physical Backup (12 Words): Traditional seed phrase backup involves writing down a 12-word phrase. This phrase is the ultimate key to your Bitcoin funds. During setup, the app prompts users to write down and verify these words, emphasizing their importance in manual recovery.
The cloud backup process is uniquely designed to be resilient against remote attacks — it separates the decryption key from the encrypted wallet file, stored on different servers, further safeguarding your funds.
