Mail PassView is a small password recovery tool from NirSoft for Windows users. It is simple, easy, and free to use. Simply download and run the program and you will recover usernames, passwords, and other important account details with no extra work from you. No installation is needed; however, this is a password recovery program and some antivirus programs will falsely flag it as a threat. There is no need to scan your computer, and after launch everything is automatic. After the program has run, you see a display of all account information from email clients that are compatible. Mail PassView works with Outlook, Outlook Express, Windows Mail, Windows Live Mail, Thunderbird, IncrediMail, Eudora and more, and it can read Gmail, Yahoo! and Hotmail passwords stored by their notifier applications. For each account you see the account name, email, server, server type (POP3, IMAP or SMTP), user name, and password. Mail PassView also offers a Copy Password command (Ctrl+P) that copies a password right from the PassView interface. You can save the selected items to a text, HTML, CSV or tab-delimited file, or export them for KeePass, so you'll never lose a password again. The best part about it, it's freeware!
