C-06: Address was copied, not typed or recalled

Why typing fails

A version three onion address is fifty six characters derived from a key rather than chosen, so there is no pattern to help you and no spell check to catch a slip. Two addresses differing by one character are unrelated services with no relationship to each other.

Why partial recall is worse than none

People remember the opening of an address because the market prefix is readable. Vanity prefixes are cheap to generate, and operators of cloned services generate addresses whose openings match for that exact reason. Recognising the first ten characters produces confidence without evidence, which is more dangerous than having no recollection at all.

What a passing session looks like

1. Open the saved source you kept before today
2. Use its copy control rather than selecting text by hand
3. Paste into Tor Browser without editing
4. Proceed to the address comparison on the login screen

Partial pass

Copying from a source you found a minute ago is better than typing and worse than using something you held in advance. It is marked partial rather than pass because the provenance question is unresolved, which the next item in this moment addresses directly.
