"In any case, the president will take part in the voting ... I do not exclude that this will be participation in electronic voting," a Kremlin spokesman told reporters.
When asked if the head of state had registered on the remote voting resource, Peskov confirmed that "the president was registered there."
Putin went into self-isolation due to cases of coronavirus infection in his environment.
Earlier, the chairman of the Central Election Commission of Russia, Ella Pamfilova, said that more than 2.6 million people have applied to participate in online voting.
