Greenaddress online Bitcoin wallet
Official URL: www.greenaddress.it
The Greenaddress Bitcoin wallet by the guys Lawrence Nahum and Jerzy Kozera contains such many great features, that there is no doubt that it’s clearly the winner of this testimonial. The website use a valid SSL certificate. That is a necessary requirement for financial transactions, and means, somebody can may see that you use Greenaddress, but transferred data are full encrypted. This encryption make sure that nobody can read your pass phrase, Balance or compromise the connection, even if you use a public WLan or similar. Additional offer Greenaddress simple access per TOR Proxy. Creating a new wallet does need neither any personal details, nor even an email address (but an email address enable more features, we will come back to this shortly). When you create a new wallet, the system protect them by a phrase with around 24 English random selected words. Please store them secured, for example in a text file on your computer, and a backup printed out. Greenaddress doesn’t store for your security this phrase, but encrypt your Bitcoin wallet with it. Hence, there is no way to restore a lost phrase and with it the wallet.
To make the wallet more protected, you have to set up a pin, a password of 4 to 15 digits. It is not needed, but strong recommended. A pin enables the way for fast login and make sure that nobody can login, even if he got your phrase. After set up a PIN, you need your long phrase only to initial log in and after three wrong PIN tries. This makes brute force attacks (trying of all possible username/password combinations) impossible. Greenaddress support for still more security two-factor-authentication using email addresses, Google authentication, SMS or phone calls. An attacker need access to your mail address or your phone to log in. This makes your online Bitcoin Wallet very secure. To make things easier, a verified mail address allow you to get always an email about received and sent transactions. Greenaddress support additional to create read-only accounts to check your balance without strong authenticates and t0 setup a Balance you will able to transfer without two-way-authenticate. This Balance will decrement each outgoing transaction and you have to reset it manually.

Blockchain online Bitcoin wallet
The Blockchain Bitcoin online wallet by the company Blockchain Luxembourg S.A.R.L. took the second place in this review. The Landing page shows already the different: While the top Greenaddress lists a lot of features, contains Blockchains only generic marketing texts. Creating a new Bitcoin wallet is fast. You have to join with an existing email address and a password of your choice. That causes in lower privacy of the as anonymous currency designed Bitcoins. The real problem are the simple login. Blockchain lacks the protection settings of Greenaddress, except two-way authentication. This makes it a bit more secure, but it misses still read-only accounts and similar. Log in into Blockchain in an unsafe environment is an absolutely no-go and a very strong password is required to avoid some attacks. Blockchain showing some Ads. They are small, but most looking very dubious. Please never follow such hyperlinks or transfer Bitcoins to a service which is not approved.
- – Moderate privacy
- – Moderate security, lacks most functions of Greenaddress
