Можно временно отключить онлайн-платежи.

Because this is an impersonal construction, which is very common in Russian.

Можно + infinitive means something like:

• it is possible to...
• one can...
• you can...
• sometimes it is allowed to...

So Russian does not need a word like you here. The sentence is naturally understood as a general statement, often like a button, menu option, or instruction.

Можно is the key word in this sentence. It can express:

• possibility — it is possible to
• permission — it is allowed to
• availability of an option — you can

In this sentence, especially if it appears in an app, website, or bank interface, можно most naturally means:

• you can
• it is possible to

So Можно временно отключить онлайн-платежи means that this action is available as an option.

This is about aspect.

• отключить = perfective
• отключать = imperfective

Here, отключить is used because the sentence refers to one complete action: disabling the payments.

So the idea is:

• Можно отключить = You can disable
• a complete, single action

If you used отключать, it would suggest:

• a repeated action,
• a process,
• or a more general habit/practice,

which does not fit as well here.

So Можно временно отключить онлайн-платежи sounds natural for a setting or feature you switch off.

Because временно describes how long the result lasts, not whether the action itself is complete.

The action is still a single completed action:

• you perform the action of disabling,
• and the disabled state lasts temporarily.

So:

• отключить = to disable (complete action)
• временно = temporarily

Together they mean: to disable them for a temporary period.

Временно is an adverb. It means temporarily.

It modifies the verb отключить, telling us in what way / for what duration the action is done.

Compare:

• временный = temporary (adjective)
• временно = temporarily (adverb)

So in this sentence, Russian needs временно, not временные or временный.

It is in the accusative plural.

Why? Because it is the direct object of отключить:

• disable what?
• онлайн-платежи

For inanimate plural nouns in Russian, the accusative plural is usually the same as the nominative plural.

So:

• nominative plural: платежи
• accusative plural: платежи

That is why the form does not visibly change.

Because after отключить, you normally need the direct object in the accusative case, not the genitive.

So:

• отключить платежи = disable payments

The form платежей is genitive plural, and it would appear in other structures, not in this simple direct-object pattern.

For example:

• нет платежей = there are no payments
• история платежей = history of payments

But here we need:

• отключить что? → платежи

In modern Russian, compounds with borrowed elements like онлайн-, офлайн-, бизнес-, etc. are often written with a hyphen when they modify a noun.

So:

• онлайн-платежи = online payments
• онлайн-магазин = online store
• онлайн-курс = online course

Here онлайн- acts like a fixed modifier and does not change form.

No, not here.

In онлайн-платежи, онлайн- is an indeclinable borrowed element used as part of a compound. It does not agree in gender, number, or case the way a normal Russian adjective would.

So even if the noun changes case or number, онлайн- stays the same:

• онлайн-платежи
• онлайн-платежей
• онлайн-платежам

Only платежи / платежей / платежам changes.

Yes, Russian word order is fairly flexible.

This version is neutral and natural:

• Можно временно отключить онлайн-платежи.

But you could also see:

• Можно отключить онлайн-платежи временно.

Both are understandable. The first one is more natural in a general neutral statement, especially in interface language.

Placing временно before the verb often makes the sentence flow more smoothly and keeps the focus on the option itself.

Yes. Можно can cover both possibility and permission.

Which meaning is strongest depends on context:

• In an app or website: usually this option is available
• In rules or instructions: sometimes this is permitted

So the sentence can carry either nuance, but in practical use it usually just means that the feature exists and the user can do it.

Both can sometimes be translated as turn off, but they are not used in exactly the same situations.

• выключить is often used for turning off devices, lights, sound, etc.
• отключить often means disconnect, disable, or turn off a service/function

For online payments, отключить is much more natural, because this is a service or feature, not a physical device.

So:

• отключить онлайн-платежи = disable online payments

sounds right.

It sounds neutral and very natural in:

• banking apps,
• websites,
• settings menus,
• help pages,
• customer service language.

It is not especially conversational, but it is not stiff either. It is standard modern Russian for a feature or option description.

A more conversational sentence might include a subject, for example:

• Вы можете временно отключить онлайн-платежи.
  You can temporarily disable online payments.

But the shorter version with Можно is very common in interface and informational language.
