Coinbase Wallet Users Can Back Up Encrypted Keys on Google Drive and iCloud

Users of Coinbase Wallet can now back up their private keys on Google Drive or iCloud, according to an official announcement on Feb. 12.
In the statement, Coinbase states that allowing users to upload their keys to a cloud provides a safeguard against lost keys, will will help them avoid losing funds should the keys be misplaced. The announcement notes:
“The private keys generated and stored on your mobile device are the only way to access your funds on the blockchain. Owners of ‘user-controlled wallets’ like Coinbase Wallet sometimes lose their devices or fail to backup their 12 word recovery phrase in a safe place, thus losing their funds forever.”
Now, users of Coinbase Wallet can store an encrypted copy of the recovery phrase on their cloud accounts. Coinbase notes that neither they nor the cloud services will have access to user funds, as recovery phrase key is unlocked by a password known only to the user. The backup is purportedly encrypted with AES-256-GCM encryption, which is only accessible through the Wallet mobile app.
