Registering new users with poetry
An acrostic is a poem (or other form of writing) in which the first letter (or syllable, or word) of each line (or paragraph, or other recurring feature in the text) spells out a word, message or the alphabet.... As a form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval.
A Person chooses a username; ascari for example.
The number of letters will be the number of lines in the poem, beginning each with a letter from the username chosen.

Points to understand
- A Person is encouraged to create and memorize a poem related to the username they have chosen.
- A username has a minimum size, say 6. Even if a user only uses a single word for each letter of the poem, the total size of the passphrase will be well over 12 characters.
- Bruteforcing should never ever succeed as there are infinite ways to encode a single username, and if a attacker targets a unique username, they would still have to deal with the unique nature of a poem created.
- There is no need to register through email, social logins, etc. The poem itself will uniquely identify the Person.
- A particular type of poem can be enforced, such as a Haiku-like structure.
- It is best not to enforce correct grammar and spelling, unless the poem has over 2 words per line.
