GreenAddress
GreenAddress is a user-friendly multi-signature wallet with improved security and privacy. At no time your keys are server side, not even encrypted. For security reasons, you should always use 2FA and the browser extension or Android App.Shared control over your money:-
This wallet requires every
transaction to be authorized both by you and this third party. Under normal
circumstances, you can regain full control over your bitcoins using your
initial backup or pre-signed transactions sent by email.
Centralized:-
This wallet relies on a
centralized service by default. This means a third party must be trusted to not
hide or simulate payments.
Remote app:-
This wallet is loaded from
a remote location. This means that whenever you use your wallet, you need to
trust the developers not to steal or lose your bitcoins in an incident on their
site. Using a browser extension or mobile app, if available, can reduce that
risk.
Two-factor authentication:-
This wallet can be used
from insecure environments. However, this service requires two-factor
authentication. This means access to multiple devices or accounts is required
to steal your bitcoins.
Basic privacy:-
Prevents spying on your payments:
This wallet makes it
harder to spy on your balance and payments by rotating addresses. You should
still take care to use a new Bitcoin address each time you request payment.
Discloses information to a third party:
This service can associate
your payments together, log your IP address and know your real identity if you
provide personal information like your email, name or banking account.
Tor can be used:
This wallet lets you setup
and use Tor as a proxy to prevent attackers or Internet service providers from
associating your payments with your IP address.
