I2 // A familiar handle to a fresh one

The password gets attention because it feels like the security decision. The username is the one that is public, permanent and trivially searchable, and most people pick one they have used for years.

Awazon Market // onion addresses

The three strings below open the same market. The same account, the same balance, the same open orders sit behind each one. Copy a string, paste it into Tor Browser, and read the last six characters in the address bar before you type a password.

NOTHING HERE IS RANKED. THE ORDER IS THE ORDER THEY WERE WRITTEN IN.

Baseline

A handle you have used elsewhere, or a variation on one, chosen because it is easy to remember.

Substitution

A name generated for this account and used nowhere else, ever.

What moves

The link between this account and everything else you have ever posted under that name.

Does not move

Anything about your session, your circuit, or the strength of your credentials.

Cost

You have to store it, because you will not remember it. That is the same manager from record I1.

Verdict

Do it, and do it before the account exists, because a username cannot usually be changed afterwards.

IWhy handles travel

People choose one name and carry it for a decade. It appears on a gaming account, a forum from 2016, a marketplace review, a code repository, a comment on a video. Searching a distinctive handle across those surfaces takes minutes and needs no special access, and it is the single most productive step available to anybody trying to connect an account to a person.

A market username is also usually visible: on reviews, on vendor pages, in dispute threads. It is not a secret and it is not treated as one, which makes reusing a familiar one an unusually cheap mistake.

IIWhat a good one looks like

Generated, not chosen. Anything you invent carries your habits: a favourite word, a birth year, a pattern you have used before.
Not descriptive of you, your city, your language, your work or your interests.
Not a variation of another handle. A suffix is a link, not a break.
Stored in the same place as the password, since you now have two strings to keep instead of one.

IIIThe related leak that is harder to stop

Writing style. Two accounts using the same greeting, the same sign off, the same spelling habits and the same shipping paragraph are connected in a way that no username choice repairs. If separation actually matters to you, the text has to change as well, which is most of what record I4 is about.

IVTiming

This is one of the few records with a deadline. A password can be replaced in a minute; a username usually cannot be changed at all after registration. If you are reading this before creating an account, the substitution is free. If you are reading it after, the honest version is to note it for the next one.

IN ONE LINE

The password protects the account. The username is the part that can be pasted into a search box by anybody, forever.
