As a marketing team, we don't have answers to this question. We know that 1xBit, 1xBet and many other bookmakers' software is produced by the same company BetB2B. In addition to software - different companies use the same service providers, for example for odds.
Some providers might deliver the same verification tokens, or there are other reasons. We can't have a confirmed answer to this question.
