walletpassphrase

walletpassphrase “passphrase” timeout

Stores the wallet decryption key in memory for ‘timeout’ seconds. This is needed prior to performing transactions related to private keys such as sending bitcoins

Arguments:

“passphrase” (string, required) The wallet passphrase
timeout (numeric, required) The time to keep the decryption key in seconds. Limited to at most 1073741824 (2^30) seconds. Any value greater than 1073741824 seconds will be set to 1073741824 seconds.

Note: Issuing the walletpassphrase command while the wallet is already unlocked will set a new unlock time that overrides the old one.

Examples:

Unlock the wallet for 60 seconds

bitcoin-cli walletpassphrase “my pass phrase” 60

Lock the wallet again (before 60 seconds)

bitcoin-cli walletlock
