On Tuesday, the site said it was to test new tools that allowed people to share any special circumstances they felt meant they could not use their real name, according to the BBC.
The tool is intended to help people who may have suffered domestic abuse, or in cases where their sexuality could put them in danger.
However, Facebook stood firm on insisting people use "real names" in all but the most unusual situations.
"We require people to use the name their friends and family know them by," the company said.
"When people use the names they are known by, their actions and words carry more weight because they are more accountable for what they say.
"We're firmly committed to this policy, and it is not changing.
"However, after hearing feedback from our community, we recognize that it's also important that this policy works for everyone, especially for communities who are marginalized or face discrimination."
