England will play in the Nations League and the World Cup in the same year.
The OneLove campaign was started by the Netherlands in order to promote diversity and inclusion.
The initiative is supported by Belgium, France, Germany, Norway, Sweden, Switzerland and Wales.
The armband will be worn by their captains at the World Cup.
Same-sex relationships and the promotion of same-sex relationships are not allowed in the country.
Kane will wear the captain's hat for the first time in a Nations League game against Italy on Friday in support of the OneLove campaign.
We stand together against all forms of discrimination because we are captains. At a time when society is divided, this is even more relevant.
A clear message will be sent when the world watches.
Migrant workers will be invited to the England training base in Al Wakrah to engage with the players.
Any injury or death related to any construction project for the World Cup should be compensated by the English Football Association, according to the association.
Up to 30,000 migrant labourers have been used on projects to build seven stadiums for the finals in the Middle East, as well as a new airport, metro and new roads.
However, Amnesty International says that since 2010, hundreds of thousands of migrant workers have faced human rights abuses while employed to build wider infrastructure necessary to host the tournament, as well as the venues.
The FA is pushing for an update on the concept of a Migrant Workers' Centre in Qatar to provide advice and help for migrant workers.
This concept will help the legislation to take effect because it is clear that it has been brought in in the last few years.
There are areas in which further support would make a huge difference to the lives of the workers in the country.
The principle of compensation for the families of migrant workers who have lost their lives or have been injured in construction projects continues to be pushed for by us.
The compensation fund is often referred to as a safety net where workers and their families have been unable to get compensation from the construction companies.
A compensation fund of at least $440 million is needed for migrant workers who have suffered "human rights abuses" during the preparations for the World Cup, according to a report by the human rights group.
Felix Jakens said that the FA's pledge to support efforts to remedy abuses suffered by thousands of overseas workers in Qatar could be significant, but we still need to see whether this is seriously taken up by the Qatari authorities or by world football's governing body.
The FA needs to support a compensation fund for abused workers and the families of those who have died in order to make the World Cup happen.
