Intel Security – which includes the McAfee unit – didn’t say how much it paid for PasswordBox, which only started business in June 2013.
It’s unclear how many of the company’s 44 employees will be employed by Intel.
Intel will give new and existing customers a premium subscription at no cost until it gets round to releasing products under its own branding.
PasswordBox has around 14 million users worldwide. The software lets you coordinate different logins and passwords in a sort of digital wallet so you don’t have to remember – or write down – all those different passwords that are easy to forget.
