In October, 2020, a Dutch security expert announced that he had been able to guess Trump’s Twitter password, “maga2020!”. Without any two-factor authentication, he was able to immediately gain full access to the account. He immediately contacted the US’ Cybersecurity and Infrastructure Security Agency (CISA) about the matter, and Trump’s password was soon after changed.

The same expert claims to have accessed Trump’s Twitter in 2016, guessing the password “yourefired”.

Twitter responded by saying, “We’ve seen no evidence to corroborate this claim, including from the article published in the Netherlands today.” Neither Trump or his campaign had any comment. A week later, The Republican Party announced that hackers had stolen over $2 million from Trump’s campaign.

Trump also refused to use secured phones, considering it “too inconvenient.”
