Muscle memory is sometimes surprising. I had a mailbox 13 years ago on a Russian service, but access to it was long lost because I did not remember the password, and the answer to a secret question was the IMEI of a long-lost phone. He then registered a new box, the name of which differs from the previous one only by the presence of a point in one place. After 13 years, I still go to my new mailbox, without thinking, I enter the login and password on the machine and logged in, I see that something is wrong. I look up and see that before me appeared an abandoned mailbox 13 years ago, but the password I still do not remember and could not repeat this trick again, but at least the old mail read))
