Twitter will begin deleting accounts that have been inactive for more than six months, unless they log in before an 11 December deadline.
The cull will include users who stopped posting to the site because they died - unless someone with that person's account details is able to log-in.
It is the first time Twitter has removed inactive accounts on such a large scale.
The site said it was because users who do not log-in were unable to agree to its updated privacy policies.
A spokeswoman also said it would improve credibility by removing dormant accounts from people's follower counts, something which may give a user an undue sense of importance. The first batch of deleted accounts will involve those registered outside of the US.
