Updated Popular password management service LastPass went on the blink today, leaving users locked out of their accounts.

Reg reader Tim Stephenson, head of IT at Liftshare, told us that the firm’s employees had experienced timeouts trying to access the site, browser plugins weren’t responding and users couldn’t authenticate themselves or access their credentials.

“We started using LP for secure password management about a year back and have a number of systems that accept LP Single Sign On for convenience. Very, very annoying and currently LP seem to be saying nothing whatsoever to their users. Disappointing as a paid-for enterprise customer,” he said in an email.

Customers also took to Twitter to complain about the service, with some claiming that the password-memory-bank had been down and out for over four hours.

@LastPass Since this morning I can't login.. 4 hours and still no response from your helpdesk. Premium member here. Can somebody care plz? — Panagiotis Kefalidis (@pkefal) August 12, 2014

LastPass seemed to be ignoring repeated tweets about the problems earlier this morning, but finally issued a message on Twitter around 2.12pm BST, two hours after Stephenson first contacted El Reg.

We're working as quickly as possible to resolve connection errors affecting a small percentage of users, we apologize for the inconvenience. — LastPass Support (@LastPassHelp) August 12, 2014

Unhelpfully, both the LastPass support pages and status page online also appear to be down, leaving folks with very few ways to contact the company. ®

Update

since the publication of this story, LastPass has been in touch to tell The Reg that the problems had been caused by one of its data centres going down at 8.57am BST this morning.

“We immediately started taking action to migrate the service to run entirely on a different data centre - in the meantime, a percentage of our user base did experience connection errors with the LastPass service,” spokesperson Amber Gott said in an email. “We have been engaged with our provider the entire time and have been working with them to resolve the issues. We have done everything we can to minimise impact and are working to get the redundant data centre up as soon as possible.”
