Hello,
Please check the setting “Wallets” -> “Cron job” -> “Withdrawal locks” -> “Time to retain secret”. If you want the passphrase to be retained indefinitely, you should keep the value at 0.
When the value is 0, the passphrase is saved into a WordPress option, while if the value is not 0, the passphrase is simply used to unlock the wallet once for the duration specified, but is not saved: https://github.com/dashed-slug/wallets/blob/4.3.4/includes/coin-adapter-rpc.php#L602-L623
If the time to retain secret is 0, the wallet is unlocked every time a withdrawal is attempted. https://github.com/dashed-slug/wallets/blob/4.3.4/includes/coin-adapter-rpc.php#L510-L551
There is nothing else that you are missing. If you have set the time to retain secret to 0, and if afterwards you have set the correct passphrase, then that’s all you need to do.
Please let me know if you have done this. I am currently double-checking if the passphrase gets deleted on my end, but this will take 24 hours for me too.
with regards
