How to unlock all accounts or unlock an account forever under parity?

Question

I want to use an account to make some transactions at the same time. So I need to unlock this account each time when I send transaction. But because it sends at the same time, it may happens that only some transactions are unlocked, the others are not...

So I think I need to unlock all accounts. Or unlock an account forever. Is there any way that I can do it?

I find that there is a config --unlock can unlock some accounts when Parity start. But my accounts are increasing. So it's not useful for me...

Can you give me some advice about it? Thanks a lot~

Answer 1

Just create a config file with:

[account]
unlock = ["0x000000000000000000000000000000000000dead","0x0000000000000000000000000000000000000000beef","0x0000000000000000000000000000000000000000cafe"]
password = ["path/to/password.file"]

This will keep all listed accounts unlocked with the password specified in the password.file.

Answer 2

Account can be unlocked by using personal_unlockAccount module of JSON_RPC. It unlocks specified account for use.

personal_unlockAccount

Unlocks specified account for use.

If permanent unlocking is disabled (the default) then the duration argument will be ignored, and the account will be unlocked for a single signing. With permanent locking enabled, the duration sets the number of seconds to hold the account open for. It will default to 300 seconds. Passing 0 unlocks the account indefinitely.

There can only be one unlocked account at a time.

Parameters

1. Address - 20 Bytes - The address of the account to unlock.
2. String - Passphrase to unlock the account.
3. Quantity - (default: 300) Integer or null - Duration in seconds how long the account should remain unlocked for.
