A plain password mechanism is not consent.

Answer A plain password mechanism is not consent. RFC 4616 describes the PLAIN SASL mechanism. The document is RFC 4616, titled The PLAIN Simple Authentication and Security Layer (SASL) Mechanism. The existence of a password login is not permission to send a solo ad. A password mechanism lets a login authenticate. It does not ask a person whether they want your letter, and it does not answer for them. If a seller treats the mechanism as a yes, the seller has renamed a login. You do not need the workings. You need the refusal.

Cream stationery and a teal accent on a dark navy desk — A password login is not a yes to a letter.

The note that started this: RFC 4616, The PLAIN Simple Authentication and Security Layer (SASL) Mechanism, RFC 4616.

People hear password and think of an account that chose to be there. An account that can log in is not a list that asked for a solo. If you are about to buy solo ads, ask who agreed to the letter, in words that name people. A pitch that starts with a password mechanism has left the product. The product is one letter to someone else's list. A login is not that letter, and it is not permission.

That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in. A buyer still has to name the list, the sending domain, and the refund line on the order. The PLAIN mechanism fills none of those blanks. A seller who opens with the password login and never names the list is handing you a public document and calling it consent. Read the document if you want. Pay only for the order.

What does RFC 4616 describe?

RFC 4616 describes the PLAIN SASL mechanism. The document is RFC 4616, titled The PLAIN Simple Authentication and Security Layer (SASL) Mechanism. The existence of a password login is not permission to send a solo ad.

The mechanism is one way a login can authenticate. That is a software fact. It is not a mailing right, and it is not a story about how to present a password. Leave the workings alone. The buyer uses one sentence from the document's neighborhood: a password login is not permission to send a solo ad. A seller who demonstrates the mechanism instead of naming the list is performing. Performance is not an audience. Ask who would receive the letter, and stop when the answer is that they have a password.

The order names who agreed to the letter.
A password mechanism is not that agreement.
The list, the sending domain, and the refund line are named.
A login is not described as the audience.

Is a plain password mechanism consent?

No. A plain password mechanism is not consent. It is a way for a login to authenticate. Authentication is not a person agreeing to receive your letter.

Consent, for this buy, is the history that lets the list owner send one letter. A password mechanism can succeed with no history you are allowed to use. Hold the success next to the order. The order should already name the list. If the only yes in the conversation is that a password login exists, there is no yes. Do not fill the gap with the specification. The specification will not mention your offer, your list, or your refund.

If you have not paid, keep the money. If you have paid and the consent story was a password mechanism, the refund line is the next sentence. On the seller side, do not offer the mechanism as proof people want mail. Offer the list, the sending domain, and the letter. A careful seller would rather lose the order than treat a login as a signature from the reader. The reader never signed that page.

Does a password mechanism prove the reader opted in?

No. That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in.

A password login does not remember a signup to your offer. It remembers that authentication can happen. People who opted in opted in to a list, which is a fact you can ask a seller to state. The mechanism is the wrong place to look. It will not hand you a rank, and it will not set a price. Ask who is on the list. Ask which domain sends. Ask what the refund line says when a password login was sold as consent, or when the list is not the list you named.

Price the object in your hand. A plain password mechanism is a login method. A solo is one letter to someone else's list. Read that difference before you argue about solo ad pricing. Pay for the letter only after the order names the list, the sending domain, and the refund line. A password mechanism is not the invoice, and it is not the audience.
