I'm using the standard Mac Bitcoin client and I added a passphrase. I'd like to remove that passphrase. Is that possible?

I don't know if the client allows you to do it without tricks, but in the worst case scenario you can still send all your coins to another address, create a new wallet, and send them back into this new one.– o0'.Commented May 6, 2012 at 18:41

I have the same problem with a wallet that is encrypted. I tried to remove it and if I reinstall a new client it comes back as the old wallet. I installed to a new location, did a registry cleaner and it comes back as the locked wallet. The trick of sending the bitcoins to another wallet don't work. It requires a passphrase to send them.– user5020Commented May 14, 2013 at 6:13

Start of Winkey + R type %appdata% and found folder Bitcoin. Save the file wallet.dat in case! Delete it form folder and the program will generate a new address for the wallet! ;)– user5024Commented May 14, 2013 at 11:14

The Bitcoin.org client does not yet have the feature to remove encryption from a wallet. You can use a single space as the encryption key but there no way to get it to no longer use encryption.
That is expected to be implemented in a future release.
In the meantime, those that want this will create a new wallet and leave it unencrypted, and send their coins from the encrypted wallet to it.

how to transfer keys from one wallet to another without transferring funds with a FEE ? Commented Feb 26, 2014 at 22:54

You can dump your old wallet to a backup file, restart the program to generate a new wallet and import your old wallet into it.
Assuming you are in the directory where your wallet file is located, using the command line that would look like this:
bitcoind walletpassphrase "xxx" 60
bitcoind dumpwallet "wallet.dat.backup"
bitcoind stop
mv wallet.dat wallet.dat.old
bitcoind -daemon
bitcoind importwallet wallet.dat.backup
I would be interested in a less dirty way, if anybody knows one.
Yes. It is possible.
Either the UI supports it or it does not. You are better equipped to find out than I am but I suspect it does not (yet).
If it does not you can either:
- Export the keys, move the wallet files (rather than deleting it, so you can move it back if things to wrong, on Mac the wallet files are here: ~/Library/Application Support/Bitcoin/), import the keys.
- implement it yourself / pay someone to implement if for you
- find an alternative client to do it for you (Armory might have it, a list is here)
- find an alternative client to open it and export the private keys, so you can import them into a new unencrypted wallet.
- when all else fails: transact your Bitcoin towards a new unencrypted wallet and ditch the old, encrypted, wallet. Be sure to tell people you've migrated, your old addresses are still in your encrypted wallet.

2* pay someone to implement it for you * use the standard client to export your keys, make a new wallet, and import the keys Commented May 7, 2012 at 5:27

I guess that's almost mentioned in the third bullet, and is the most obvious answer. I'll correct. Maybe I didn't really understand the question last time?– LodewijkCommented Dec 11, 2014 at 12:54
