Twitter is planning to introduce two-step authentication process following a series of hacking incidents.

Citing an unnamed person familiar with the matter, Bloomberg reported that two-step authentication will be introduced to make it difficult for outsiders to gain access to an account.

Earlier this year, Twitter became the victim of cyber-attacks with "extremely sophisticated" hackers, who have reportedly stolen user names and passwords for about 250,000 users.

However, the micro-blogging website, which has 200 million active users per month, said passwords for the affected accounts were reset after the attack.

Recently, many users, companies and several news agencies have reported that their Twitter accounts have been hacked.

CBS News suspended two of its twitter accounts after they were hacked while a number of BBC Twitter accounts were also hacked in past months.

Associated Press (AP) has also reported that its Twitter account had been hacked by a group called the Syrian Electronic Army.

Earlier this month, Microsoft said it will upgrade 700 million of its user accounts including rolling out of an optional two-step verification to offer better security.

Last month, Apple added a new level of security to iCloud and Apple ID accounts which requires two-step verification to prevent passwords from being stolen.
