Одноразовий пароль не є реквізитами картки.

• одноразовий = one-time, single-use
• пароль = password

So одноразовий пароль is a one-time password or an OTP.

The adjective одноразовий agrees with пароль:

• masculine
• singular
• nominative

because пароль is a masculine singular noun here.

є is the present-tense form of бути (to be), so не є means is not.

So:

• Одноразовий пароль не є... = A one-time password is not...

In Ukrainian, the present-tense to be is often omitted in everyday speech:

• Він лікар. = He is a doctor.

But є is still used, especially in:

• formal writing
• definitions
• warnings
• official or careful statements

This sentence sounds formal and precise, which fits a banking/security context.

After є (is) in formal Ukrainian, the noun that names what something is / is not is often put in the instrumental case.

So:

• nominative: реквізити
• instrumental plural: реквізитами

That is why the sentence has:

• не є реквізитами картки

This is a very common pattern in more formal Ukrainian:

• Він є студентом. = He is a student.
• Це не є проблемою. = This is not a problem.

Here, because реквізити is plural, the instrumental form is also plural: реквізитами.

Because реквізити картки means card details, and that idea is normally expressed as a plural set of details.

The sentence is saying that one item, the one-time password, is not the same thing as the card details.

So the mismatch is normal:

• singular subject: одноразовий пароль
• plural predicate noun: реквізитами картки

English does something similar:

• A one-time password is not card details.

In banking language, реквізити картки is a fixed phrase, so the plural is natural.

In this context, реквізити картки means card details or card credentials/information.

Usually this includes things like:

• the card number
• expiration date
• CVV/CVC
• sometimes the cardholder’s name

So the sentence means that a one-time password should not be treated as part of those card details.

картки is the genitive singular form of картка (card).

This is a very common Ukrainian pattern:

• noun + noun in genitive = X of Y

So:

• реквізити картки = details of the card = card details

Other similar examples:

• номер телефону = phone number
• сторінка книги = page of the book
• центр міста = city center

Ukrainian has no articles like a or the.

So пароль can mean:

• a password
• the password

Context tells you which one is meant.

In this sentence, English might translate it as either:

• A one-time password is not card details
• The one-time password is not card details

In a general warning, English usually uses a one-time password.

Yes, it sounds fairly formal and official, which is normal for a security or banking message.

The main things that make it sound formal are:

• не є
• the careful noun phrase реквізитами картки

In more conversational Ukrainian, people might prefer wording such as:

• Одноразовий пароль — це не реквізити картки.
• Одноразовий пароль не належить до реквізитів картки.

But the original sentence is perfectly understandable and appropriate in official communication.

Yes, Ukrainian often leaves out the present-tense to be, especially outside very formal style.

So you may also see:

• Одноразовий пароль — не реквізити картки.
• Одноразовий пароль — це не реквізити картки.

However, не є sounds more explicit and formal, so it works well in warnings, instructions, and legal/official text.

It is in the nominative case, because it is the subject of the sentence.

Breakdown:

• одноразовий — masculine singular nominative adjective
• пароль — masculine singular nominative noun

They match each other in:

• gender
• number
• case

That agreement is a basic feature of Ukrainian adjectives and nouns.

Not always. Реквізити has a broader meaning like details, particulars, or official information needed for identification/payment.

In different contexts it can mean:

• bank details
• company details
• document details
• card details

So the exact translation depends on context. In this sentence, because of картки, it clearly means card details.
