1Password is a password manager developed by AgileBits Inc. It provides a place for users to store various passwords, software licenses, and other sensitive information in a virtual vault that is locked with a PBKDF2-guarded master password. By default, this encrypted vault is stored on the company's servers for a monthly fee.
Password file syncing
1Password can be configured so that files are synchronized through Dropbox (all platforms), local Wi-Fi, and iCloud, and through 1Password.com, a paid subscription-based server sync service maintained by the developers. Local Wi-Fi and iCloud sync are only available on iOS and macOS.
In 2017, the Travel Mode feature was introduced for subscribers of 1Password.com, which enables omission of password entries not tagged as safe for travel from the local storage on a particular device, reducing the impact of being obliged by officials to unlock access at country border crossings.
1Password integrates with desktop web browsers including Safari, Chrome, Firefox, Edge, and Opera. The extension can remember logins for websites, fill in website logins automatically, and generate random passwords for new websites.
To use browser extensions, the user must have administrative rights on the computer where the browser is installed. This has been an issue with users on a PC assigned by a workplace without admin rights. To address this issue, 1Password offers plans for a monthly subscription fee aimed at businesses that allows web access to their usernames and passwords which can be copied and pasted into login screens. Plans for family and individual use are also available.
1Password also offers a standalone extension called 1Password X, available for Firefox, Chrome, and Opera. 1Password X is designed to work without a companion desktop app, but a 1Password.com subscription is required.
On the mobile side, 1Password offers integration with browsers and apps on iOS and Android devices using various methods. More convenient methods of filling and saving login information are provided in iOS 12 and Android Oreo (and later), respectively.
In a 2017 Consumer Reports article, Dan Guido, the CEO of Trail of Bits, listed 1Password as a popular password manager (alongside Dashlane, KeePass, and LastPass), with the choice among them mostly up to personal preferences.
Before 1Password 7, and the move to a purely subscription-based service in 2018, 1Password could be set up to only store password files locally, and not sync with remote servers, after purchasing a software license ($64.99 in 2018). As per Dec 2019, Mac users can still buy a perpetual licence of 1Password 7 from within the app. Apple's browser Safari v13 makes the installation of the 1Password extension v6 impossible, thus forcing users to upgrade to 1Password v7.
On November 14, 2019, 1Password announced a partnership with venture capital firm Accel, which invested $200 million in a Series A funding round and obtained a minority stake in the company. It was the first outside funding in 1Password's history, and the largest single investment Accel had made to date.
