Twitter is forcing users of sensitive US accounts, at risk of being targeted by hackers during the election period, to use a strong password.

These include accounts linked to presidential campaigns, political parties and political candidates, the company announced on its blog on Thursday.

According to Twitter, a strong password contains at least ten characters and is a random mix of uppercase, lowercase letters, numbers and symbols.

The longer a password is, the more secure the account is.

Twitter will notify users of sensitive accounts that must comply.

Selected users with a weak password will need to change it the next time they log in.

Users will also be asked to enter an email address or phone number to reset the password.

This protects the accounts against unsolicited attempts from outside to change the password.

The password refresh can then only be requested with the extra information.

“Although we require some accounts to do so due to the sensitivity of the election period, anyone on Twitter can use these security measures,” Twitter writes.

The company also encourages its users to do so.
